L A B O V E R V I E W Scenario/Summary This lab will introduce you to the processes involved in defining one of the key components of a data model; the relationship diagram (RD). In this lab, you will draw a relationship diagram for two of the steps shown. Keep in mind when you are trying to decide which side of the relationship should be the "one" side and which should be the "many" that
you must first decide which side has the primary key, or unique identifier. Once you have decided the primary key of the relationship, you have identified the "one" side of the relationship. Note that for an RD, the foreign key "many" side of the relationship points to the primary key "one" side. The "one" side should have the arrowhead point of the connecting line. This is different than an entity/relationship diagram (ERD) that we will draw next week, where the "many" side has crow's feet. This will familiarize you with how to set up MS Visio to draw database diagrams. Steps 1 - 3 below use the Customer, Order, and Employee tables of a simplified Order Entry database. The Customer table records clients who have placed orders. The Order table contains the basic facts about customer orders. The Employee table contains facts about employees who take orders. The primary keys of the tables are CustNo for Customer, EmpNo for Employee, and OrdNo for Order. The following are the TABLE definitions for the first three tables showing the PRIMARY KEY constraints. TABLE Customer has the following attributes CustNo NUMBER(5) CustFirstName VARCHAR2(20) CustLastName VARCHAR2(30) CustCity VARCHAR2(30) CustState CHAR(2) CustZip CHAR(10) CustBal NUMBER(12,2) CustNo is the PRIMARY KEY TABLE Employee has the following attributes EmpNo NUMBER(5) EmpFirstName VARCHAR2(20) EmpLastName VARCHAR2(30) EmpPhone CHAR(15) EmpNo is the PRIMARY KEY TABLE Order has the following attributes OrdNo NUMBER(5) OrdDate DATE CustNo NUMBER(5) EmpNo NUMBER(5) OrdNo is the PRIMARY KEY Your task for this lab is to create the required relationship diagram for steps 1 and 2 using Microsoft Visio. Step 3 will require you to analyze the scenario given and present your own resolution to the question. Step 4 is an individual assignment that will introduce you to the group project and the process of identifying entities and attributes. When finished with the lab, you should have a complete diagram using all 5 entities, a written explanation for #3, and two lists (entities and attributes) for Step 4. Deliverables The deliverable for this lab is a single MS Word document named "Lab1_solution_yourname" with the diagram for problems 1 and 2, the written answer for the question in Step 3, and the lists of entities and attributes for the Initial Project Exercise (Step 4). You should copy and paste the diagram from MS Visio into a Word document and use this document for Steps 3 and 4. L A B S T E P S STEP 1: Drawing your first ER diagram Title Identify the foreign key columns in the table structures above and draw a relationship diagram depicting the relationships between the tables. In the Order table , the CustNo column references the Customer table and the EmpNo column references the Employee table. For each relationship, identify the table on the "1" side of the relationship and the table on the "Many" side. STEP 2: Extending the ER diagram Extend your relationship diagram from problem 1 by adding two tables (OrdLine and Product). Table definitions for the table structures and primary keys constraints are shown below. You will need to identify the FOREIGN KEY(s) to complete this problem. When finished you should have a total of 5 tables represented in your diagram for this problem. To copy and paste the diagram into Word, select Edit from the menu and then Copy Diagram. Open a Word document and use CTRL-V to paste the diagram. TABLE Product has the following attributes ProdNo CHAR(8) ProdName VARCHAR2(20) ProdNo is the PRIMARY KEY TABLE OrdLine has the following attributes OrdNo CHAR(8) ProdNo CHAR(8) Qty NUMBER(5) The combination of OrdNo and Prodno is the PRIMARY KEY STEP 3: Should a NULL be allowed? From examination of the sample data and your current understanding of businesses in which orders could be placed either in person, over the phone, or over the Internet, determine if it would be permissible for null values to be allowed for the foreign key EmpNo in the Order table. This column would reference back to the EmpNo column in the employee table. Why or why not? OrdNoOrdDateCustNoEmpNo O1656777 02/11/2000 C8543321 O7959898 02/19/2000 C8543321 E8544399 STEP 4: Initial Project Exercise Although the overall project itself will be done as a group, this first exercise is designed as an individual effort and is intended to; (1) get you to read the project specifications, and; (2) introduce you to the first step in designing a database from scratch. This little exercise will have you see how many entities and attributes you can find in the project specifications. In week three, you will work with your assigned project team and compare notes on what you have found. This is not rocket science here so remember, you are looking for people, places, things, and events (entities) and the attributes that describe them.

Lab two introduces the next step in creating a data model, the Entity Relationship Diagram (ERD). You will be given a business scenario for a company named Clapham Specialty Store, which is a small specialist grocery and delicatessen. The business specifications will outline a number of things about the business, some of which will apply directly to the database you are being asked to model. There is a table which lists the entities (tables) that will be needed for the database and related attributes (columns) for each entity. There is also a column that lists specific information about the entity that will be helpful in determining its relationship to other entities within the model. Be sure to include the minimum and maximum occurrences of each relationship (cardinality) and to supply a name to the relationship that will work in both directions. If there is not a single word that will apply, then supply a separate name for each direction of the relationship. Narrative/Case Study TheClapham Specialty Store is a small, specialist grocery and delicatessen. A new owner, John Balfour, who would like to expand the store and improve its profits, has recently purchased the store. The store sells general groceries, wines and liquors, and has a small deli counter. The store is open from 5:00 a.m. to 12:00 midnight. Many of the customers are repeat customers who come in to buy products they forgot from their regular grocery shopping expedition at the supermarket. The store sells about 3,000 different products ranging from toilet cleaner to 2 oz. jars of caviar, and champagne to liverwurst. Each product is displayed on a shelf on one side or the other of the aisle. The products arrive and their details (cost, quantity, SKU number, package size, purchase date) are recorded in the back room before they are displayed. The new owner wants to know which products the store sells most of and which are the most profitable. The following is some general information about the company and its current processes. The store has 3 cash registers. Between 3 and 7 employees will work at any given time, depending on the time of day and how busy they are. An employee logs in to the register at the start of a shift and logs out at the end. The name, address, Social Security number and other information is recorded for every employee. All employees are paid weekly against an hourly rate which varies depending on their job description. Each sale is identified by a Receipt No. and a timestamp (date and time) and consists of sale items with a quantity and price recorded for each product. As a convenience for known customers, they offer a local delivery service. Deliveries are only made to customers who are registered at the store; walk-ins must record their name, address, and phone number before a delivery can be made to them. John can find the cost of the goods from the accounts system. What John would like to have is a point of sale system (POS) that records what has been sold to whom, by whom, for how much, and when. Also, he needs to be able to record the delivery trips that are made, who makes the delivery, how long the delivery takes, and the amount of the sale. There is concern at this point that the cost of delivering the sales to customers is not worth the return on investment. Requirements: You have been asked to develop a logical data model for Clapham Specialty Store based on the information given to you by John and his staff. Through analysis of the nouns and verbs in the case study above, you have accumulated the following entity, attribute, and relationship information shown in the table below. The attribute list may not be complete. If you determine that additional attributes are needed to better define an entity then you should add them. Entities Attributes and Relationships for Clapham Store: Entity Attributes Relationships Employee ID Number, Last Name, First Name, Phone Number, Employee Type ID An Employee can belong to any one of the three job categories, but can belong to one and only one of the three. Employees have names and other contact information. Employee Type Type ID, Description, Hourly Pay Rate An employee can be either a clerk, delivery person, or a supervisor. Register Log Register Log Number, Register Number, Log In Time, Log Out Time, Employee ID Sales are made using a register and can be tracked by the register log number. An employee must log into the register before he/she can use it and must log out when finished with a shift at that register. An employee may use more than one register during a period of work. Register Register Number, Register Location Description, Register Serial Number The store has 3 registers: One located at the back of the store and two located at the front of the store; one on the left and one on the right of the entrance. Deliveries Delivery Number, Employee ID, Sales Receipt Number, Time the Employee Left and Returned Relates to both the employee and the sale entities. This entity will help track deliveries. An employee can make many deliveries but a sale is delivered by one and only one employee. Location Location ID, Aisle, Side, Shelf Relates to product and identifies one or more areas of the store where products are displayed. Product Product ID, Name, Package Size, Cost, Quantity on Hand (QOH), Last Purchased Date, Reorder Minimum Identifies the products the store sells. One or more products can be sold per sale. The quantity on hand allows John to determine his inventory levels. The reorder minimum can be used to determine when the inventory level has reached a reorder point. Sale Receipt Number, Sales Amount, Sale Date- Time A sale is identified by a single receipt. Sales are: made to one or more Customers but only one customer at a time. made by one or more Register Clerks but only one clerk per sale. recorded on one or more Registers but only one register per sale. delivered by one or more delivery persons but no one sale can be delivered by more than one delivery person. Sold Items Receipt Number, Product ID, Item Price, Quantity Sold Sale Item is part of sale and records product sold per sale. Sale item must be able to associate multiple products sold on a single sales receipt. Customer Customer Number, First Name, Last Name, Address, Phone Number A customer can be associated with multiple sales, but any one sale is to one and only one customer. A sale can occur without a customer registering in the system. Using MS Visio, develop an ERD that meets the following guidelines: Draw the entities with their attributes. Indicate the relationships between the entities using Crow's Foot notation. You will need to determine the cardinality and optionality for each direction of the relationships. Some of the Foreign Key relationships are identified in the graph above but not all. Be sure you identify and account for all Foreign Key relationships. Add a name (in both directions) to the relationships. Remember, if you can verbalize the relationship in both directions then you probably have a valid relationship. Deliverables The deliverable for this lab will be your completed ERD as a single MS Word document using copy/paste from the MS Visio application and named "lab2_solutions_yourname". L A B S T E P S STEP 1: Drawing entities and attributes Be sure to include all of the entities that have been defined. You need to include at least the primary and foreign key attributes where applicable in your diagram. STEP 2: Indication of all relationships Be sure that you link all entities based on PK to FK relationships. There may be a case where you need to identify a combination PK and if so make sure that all of the relationships involved are defined. Be sure that you have set your Visio editor to show Crow's Foot notation. Also, be sure that you are defining the correct cardinality for the relationships. STEP 3: Naming of relationships Do not accept the default naming convention for your relationships in all cases. There may be some relationships where this is applicable, but in most cases you will want to explicitly name the relationship. Be sure that you have provided a verb phrase for both directions in the relationship. This is the end of lab #2

CIS 336 CIS336 Week 3 iLab 3 Devry University

Beginning with this lab, and continuing through the remaining weeks you will be doing all of your work in Oracle itself. The editor interface to the Oracle server is SQL*Plus, and by now you have received your logon ID and password and should have at least made sure you can connect. If for any reason you have not done so, please do so now before continuing any further. If for any reason you cannot connect then you need to let the instructor know ASAP so that any problems can be resolved. Before attempting Lab #3, you need to be sure you have read through the SQL*Plus tutorial which can be found in Doc Sharing as well as under the SQL*Plus Tutorial tab in Week 3. This tutorial describes the functionality of the editor and will take you through the process of setting up and using the SQL*Plus in the iLab environment so that it will best serve your needs for the remainder of the labs required for this course. The lab for this week addresses taking a logical database design (data model) and now transforming that into a physical model (tables, constraints, and relationships). As part of the lab, you will need to download the Zip file titled "Lab 3 Support Documents" from Doc Sharing. This Zip file contains three documents: Lab 3 Relationship Diagram.docx, Lab 3 Meta Data Diagram.xlsx, and Lab 3 Input Data.docx. Your job will be to take the meta data defined in the data dictionary spreadsheet document, and using the relationship diagram as a guide define the table structures and constraints using both CREATE TABLE and ALTER TABLE statements. Once this has been done, you will need to write the INSERT INTO TABLE statements to insert the data provided into the table. The data should verify that the constraints you have created are valid and define the correct referential and data integrity constraints asked for. Lastly, you will write SELECT statements to query the tables and verify the data was populated. Narrative/Case Study For this lab, you be working with command-line SQL to build a series of relational tables, using SQL CREATE statements in a script file format for the Student Database and then populate those tables through the use of INSERT statements with sample data. You will need to create a script file and name it YourName_Lab3.txt containing the following code: The drop table statements listed later in the specifications of this lab. The CREATE TABLE statements required to build the seven (7) tables. The INSERT statements necessary to insert all of the sample data. Seven select statements to verify that the data is in the tables and accessible. To help you accomplish this task successfully, you are being supplied with the following three documents which can be found in the Doc Sharing tab on the course website: A Relationship Diagram of the database showing in graphical form the 1:M relationships between the tables (336_Lab3_Relationship_Diagram.doc). A Meta Data chart providing information about table names, column names, etc. Be sure to follow this reference exactly when constructing your CREATE TABLE statements (336_Lab3_Data_Dict.xls). A listing of sample data to use when writing the INSERT statements to populate the tables (336_lab3_input_data.doc). The following guidelines are being provided to help assist you in creating your script file: Create the tables in the order shown in the data dictionary. Use the names for the tables and columns as listed in the Meta Data chart – Do not change them as it will affect your grade. Creating CONTRAINTS - Create all constraints as indicated in the data dictionary. Constraint suffixes must be as follows: Primary key constraint – PK Foreign key constraint – FK Check constraint - CC Explicitly name all constraints PRIMARY KEY, FOREIGN KEY, and CHECK constraints to reflect: TableName_ColumnName_ConstraintSuffix (For example, to name a PRIMARY KEY constraint on the SID column in the student table you would use STUDENT_SID_PK.) For this lab you do not have to explicitly name NOT NULL constraints Create all PRIMARY KEY and NOT NULL constraints within the CREATE TABLE statements at the column level (line level), unless the Primary Key is a composite Primary Key (yes, there is one). Composite Primary Key constraints must be created at the table level. Create all FOREIGN KEY and CHECK constraints at the table level using ALTER TABLE statements. All constraints must be added prior to populating the tables with data. Create all of the tables and all of the constraints before populating any of the tables with data. Insert statements must be in the same order as the tables are created (follow the order in the sample data file). ALL character strings must be enclosed in single quotes. This includes alpha strings and alphanumeric (remember that any formatting within a numeric strings makes it alphanumeric). If you are inserting a NULL, do not enclose the word NULL in single quotes, as this will insert the word NULL into the row. To insert a null you simply use the word NULL. Deliverables The deliverable for this lab will include the following documents. Your script file. Create this file in Notepad not Word. Make sure your name is in a comment area at the top of the script file. Use a double dash to create a one line comment: --Jacob Smith --Lab 3 Your lab output file created using a spool session in SQL*Plus. Be sure to use the SET ECHO ON session command when creating the output file so that both the SQL commands and results will show in the output. Be sure your name is on all documents and that all documents have been included in a single Zip file for this week’s assignments. L A B S T E P S STEP 1: The DROP statements The following DROP TABLE statements must appear at the top of your script file. This will allow you to run and re-run your script file as often as you need to. The first time you run your script file you will get an ERROR on the drop statements saying the Table or View does not exist. This is true since it has not been created yet, but the error is more informational than anything. Once the tables are created, you will not get this error again. DROP TABLE ENROLLMENT CASCADE CONSTRAINTS PURGE; DROP TABLE COURSE_SECTION CASCADE CONSTRAINTS PURGE; DROP TABLE COURSE CASCADE CONSTRAINTS PURGE; DROP TABLE TERM CASCADE CONSTRAINTS PURGE; DROP TABLE STUDENT CASCADE CONSTRAINTS PURGE; DROP TABLE FACULTY CASCADE CONSTRAINTS PURGE; DROP TABLE LOCATION CASCADE CONSTRAINTS PURGE; STEP 2: The CREATE TABLE statements Next, define the CREATE TABLE statements for the seven tables that you are to create based upon the ERD and Data Dictionary that you have been given for this lab. Be sure to follow the guidelines given above on how and where to create the different types of constraints for each table. STEP 3: The INSERT statements for the data The third step is to create the insert statements to insert the sample data into the tables created in Step 2. You might find it helpful to take the Word document containing the sample data and save it as a text file. After doing this, you could create the insert statements around the actual data that is in that file. The process for doing this should have been covered in one of the lectures for this unit. If it was not, then ask your instructor to discuss this process with the class. STEP 4: The SELECT statements The next step of the lab will be to create the select statements to verify the data was inserted correctly. You should have seven select statements; one for each table. The command is SELECT * FROM Table_Name; For example, to select all columns from the Student table, the command would be SELECT * FROM Student; Be sure to save all of the above statements in your script file. STEP 5: Testing and verifying your script Now we come to the point of verifying that your script file works by creating all of the tables and inserting all of the data. To verify this you will need to execute your saved script file and create an output file to capture the results being returned to the session by using the spool COMMAND outlined in the tutorial "Using Oracle SQL*Plus." This output file will be one of the files you will be turning in for grading.

Lab 4 of 7: Building the Physical Model (28 points) Submit your assignment to the Dropbox located on the silver tab at the top of this page. For instructions on how to use the Dropbox, please click here. (See Syllabus/"Due Dates for Assignments & Exams" for due dates.) L A B O V E R V I E W Scenario/Summary Lab #4 will introduce the various aspects of the SQL select statement and the methods of retrieving data from the database tables. The lab will utilize a set of tables found in the script file (LeeBooks.sql) found in the Doc Sharing area of the website. You will need to download the file, then run the script in your SQL*Plus session. These tables will be used for the remaining labs in this class. The SELECT statement is the primary means of extracting data from database tables, and allows you to determine exactly which data you want to extract by means of different comparison operators used in the WHERE clause. This includes the use of specific "wild card" characters which allow you to search for character or number patterns within the data. You can also perform mathematical expressions within the SELECT statement to create derived output. The ORDER BY clause allows you to sort the output data in either ascending (the default) or descending order. Lab #4 will explore all of these applications of the SELECT statement. General Lab Information and Considerations Each query in the script file you will create must be numbered (use - -1 comments for numbering) and listed in order. The SQL for the following exercises should be written using Notepad and run in SQL*Plus. Read each problem carefully and follow the directions as stated. A Clean Script File: A script file is meant to be like a program. The file can be run every time the code needs to be executed without having to retype the code again each time. For this reason, it is important that there are no errors in the code inside the file. You can go back and forth between Notepad and Oracle when creating your script file to check your queries and verify if they work or not, but you do not want to create your final output file until after you have verified that everything in your script is correct by running it, in its entirety at least once and viewing the output. Once this has been done, you can create your final output file, with echo on to create the document you can turn in with your lab. Remember in using a spool session, you must type "SPOOL OFF" at the SQL> prompt after your script stops spooling to capture all of your data! Lab Do's and Don’t's Do Not include the LEEBOOKS.SQL as part of your lab script. Do use Notepad to write your query script file. Do Not write your queries in Word. Do test each query before moving on to the next. Do Not include extra queries for a problem unless the problem explicitly asks for more than one query. Do test your queries before creating your final output file. Do Not turn in a script file that has queries with errors. Do number each query using - -1 comment notation. Do Not start your query on the same line as the comment. Do remember to check your final output and script file for accuracy. Do Not turn in your lab without first checking your output file to verify that it is correct. Things to keep in mind: If you are not sure of the table names in your user schema, you can use the following select statement to list them. SELECT * FROM TAB; If you want to know the name of the columns in a particular table, you can use the following command to list them. DESC Making a script file containing a series of describe statements for each table and then spooling the output will give you a listing of all the tables with column names. Be sure to review and verify your final output when you are finished. DO NOT assume anything. Write queries for each of the stated problems in the steps below that will return a result set of data to satisfy the requirements. When finished, your script file should have a total of 13 queries and your resulting output file should show both the query and result set for each. Deliverables The deliverable for this lab will include: Your script file with the 13 queries in it. Be sure your name, course number, and lab number are in a comment area at the top of your file. An output file created using SET ECHO ON showing both the SQL code and the results. Both documents are to be zipped into a single file before submitting to the iLabDropbox for Week 4. L A B S T E P S STEP 1: Using the BOOKS table, write a query that will list the categories for the books in inventory. List each category only once in your result set. STEP 2: Using the BOOKS table, write a query that will list the title and publisher ID for each book in the table. Use the column heading of "Publisher ID" for the pubid field. STEP 3: Using the BOOKS table, write a query that will list the book title, retail price, and the amount of markup for each book. The amount of markup is the retail price minus the cost. Use the column heading “Price Markup” for the arithmetic expression column. STEP 4: Using the BOOK_CUSTOMER table, write a query that will list the customer’s first name, last name, and city for those customers living in zip code 31206. STEP 5: Using the BOOK_ORDER table, write a query that will list everything about the orders placed prior to April 2, 2009. STEP 6: Using the BOOK_ORDER table, write a query that will list everything about the orders that have not been shipped yet. STEP 7: Using the BOOK_CUSTOMER table, write a query using the AND and OR operators that will list the customer information for those customers living in either Florida or New Jersey who have not been referred by another customer. STEP 8: Using the BOOKS table, write a query that will list all information about those books that are not computer books and do not cost more than $30.00 retail. STEP 9: Using the AUTHOR table, write a query that will list all information about authors whose first name ends with an “A”. Put the results in descending order of last name, and then ascending order by first name. This should be done using a single query. STEP 10: Using the BOOK_ORDER table, write a query using the > and < operators="" that="" will="" list="" the="" orders="" that="" were="" placed="" between="" april="" 1,="" 2009="" and="" april="" 4,="" 2009.="" only="" show="" the="" orders="" for="" april="" 2nd="" and="" 3rd="" in="" your="" result="" set.="" step="" 11:="" using="" the="" book_order="" table,="" write="" a="" query="" that="" will="" list="" the="" orders="" that="" were="" placed="" between="" april="" 2,="" 2009="" and="" april="" 4,="" 2009="" including="" those="" placed="" on="" the="" 2nd="" and="" 4th.="" use="" a="" different="" approach="" (operator)="" in="" writing="" this="" query="" than="" used="" in="" the="" query="" for="" #10,="" that="" is,="" do="" not="" use=""> and < signs="" in="" your="" query.="" step="" 12:="" using="" the="" books="" table,="" write="" a="" query="" that="" will="" list="" the="" book="" title,="" publisher="" id,="" and="" published="" date="" for="" all="" books="" that="" were="" published="" by="" publisher="" 4="" or="" after="" january="" 1,="" 2001.="" order="" the="" results="" in="" ascending="" order="" by="" publisher="" id="" and="" give="" the="" publish="" date="" and="" publisher="" id="" columns="" meaningful="" titles.="" step="" 13:="" many="" organizations="" use="" percentage="" of="" markup="" (e.g.,="" profit="" margin)="" when="" analyzing="" financial="" data.="" to="" determine="" the="" percentage="" of="" markup="" for="" a="" particular="" item,="" simply="" subtract="" the="" cost="" for="" the="" item="" from="" the="" retail="" price="" to="" obtain="" the="" dollar="" amount="" of="" profit,="" and="" then="" divide="" the="" profit="" by="" the="" cost="" of="" the="" item.="" the="" resulting="" solution="" is="" then="" multiplied="" by="" 100="" to="" determine="" the="" percent="" of="" markup.="" using="" a="" select="" statement,="" display="" the="" title="" of="" each="" book="" and="" its="" percent="" of="" markup.="" for="" the="" column="" displaying="" the="" percent="" of="" markup,="" use="" “markup="" %”="" as="" the="" column="" heading.="" this="" is="" the="" end="" of="" lab="" #4="">

Lab 5 of 7: Retreiving data from Multiple Tables (28 points) Submit your assignment to the Dropbox located on the silver tab at the top of this page. For instructions on how to use the Dropbox, please click here. (See Syllabus/"Due Dates for Assignments & Exams" for due dates.) L A B O V E R V I E W Scenario/Summary Lab 5 deals with writing queries using multiple tables as covered in the reading and lecture material this week. In some cases, you will be given the option to write a query using either the TRADITIONAL method of joining tables or using the JOIN key word. In some cases, you will be asked to use a specific approach. Using the incorrect process when the process is specified will result in points being taken off for that problem. The SELECT statement is the primary means of extracting data from database tables, and allows you to determine exactly which data you want to extract by means of different comparison operators used in the WHERE clause. This includes the use of specific "wild card" characters which allow you to search for character or number patterns within the data.

Both documents must be zipped into a single file before submitting to the iLabDropbox for Week 5. L A B S T E P S STEP 1: Using the BOOKS and PUBLISHER tables, create a query using the traditional join method that will return a list containing the book title, publisher contact person, and publisher phone number for all publishers whose publisher name starts with an ‘R’. STEP 2: Using the DUAL table, create a query that will return the day of the week, hour, minutes, and seconds of the current date setting on a computer. The day should be in all upper case. STEP 3: Using the BOOK_CUSTOMER and BOOK_ORDER tables, create a query using the NATURAL JOIN method that will return a list containing the customer first name and last name and the order number for all orders that have been shipped. Give the customer name column an alias of "Customer Name" and order the output by the customer number in the BOOK_ORDER table in ascending order. STEP 4: Using the BOOK_ORDER table, create a query that will return the order number, order date, shipping address, city, state, and zip code for all orders going to Atlanta or Austin. Format the order date to display as Month DD, YYYY and give the column an alias of "Date Ordered". Be sure the month begins with a capital letter. STEP 5: Using the BOOK_ORDER table, create a query using the correct function to return the order number, the date ordered, the date shipped, and a column representing the number of months between the two dates for all columns where a date shipped exists. Format the number returned from the function to display only two decimals, and give the column an alias of "Months Between". NOTE: Be sure that all of the numbers in the fourth column are positive numbers. STEP 6: Using the correct tables in your schema, create a query using either join operation that will list the title of each book and author name(s). Give the title column an alias of "Book Title". Sort the results by title and then by author last name. STEP 7: Using the BOOKS table, create a query that will return the book title, cost, and retail price for all books with a title starting with the letter ‘H’. Use the correct conversion function to format the cost and retail columns to show dollars and cents with a dollar sign (e.g., a price of $25 would display $25.00 in the result set). STEP 8: Using the BOOK_ORDER, ORDER_ITEMS, and BOOKS tables, create a query using an OUTER JOIN operation that will list the book title, order date, and order number for all books in the BOOKS table. Order your output in descending order by ORDER_ITEMS.BOOKID. There are three books that have never been ordered which should show up at the top of your listing. STEP 9: Using the correct tables, create a query using the traditional join operation that will list the customer first and last name, book title, and order date (formatted as MM/DD/YYYY with an alias of “Order Date”) for all the customers who have purchased books published by 'PRINTING IS US'. STEP 10: Using the BOOKS and ORDER_ITEMS table, write a query using the correct Relational Set Operator that will show all of the Book IDs in the BOOKS table that have not been ordered. STEP 11: Using the BOOK_CUSTOMER, BOOK_ORDER, ORDER_ITEMS, and BOOKS tables, create a query using traditional join conditions based on comparisons between primary and foreign keys that will list the customer number, first and last name, and book title. Limit your listing to only those books in the ‘FITNESS’ category. STEP 12: Using the BOOKS, ORDER_ITEMS, and BOOK_ORDER tables, create a query that will list the title, retail, quantity, and order date for all books ordered after April 30, 2009. STEP 13: Using the correct tables, create a query using either join operation you wish that will list the order id, order date, quantity ordered, and retail price for every book that has been ordered. Format the date as MM/DD/YYYY with an alias of “Order Date” and format the retail price column using the correct function to show dollars and cents with a dollar sign ( $ ) and a column alias of “Retail”. This is the end of lab #5

Week 6. L A B S T E P S STEP 1: Back to top Using the BOOK_CUSTOMER table and the NVL function, create a query that will return a list containing the customer number, first name, last name, and the characters ‘NOT REFERRED’ if the customer was not referred by another customer. Give the derived column an alias of REFERRED BY. Do not list any customers that were referred by another customer. STEP 2: Back to top Using the BOOKS table and the SUBSTR function, create a query that will return a list of book ISBN codes and the book title for all the computer books. Format the ISBN code to display as 9-999-99999-9 (e.g., 1059831198 would display as 1-059-83119-8) STEP 3: Back to top Using the BOOKS table, create a query using the correct functions to return the category name, the total retail of all books per category with a column alias of "Total Retail", and the average retail of all the books per category with an alias of "Average Retail" for all categories with a total retail greater than $40.00. Format the total retail and average retail columns using the correct function to show dollars and cents with a dollar sign. STEP 4: Back to top Using the correct tables in your schema, create a query using either join operation you wish that will list the book title and number of authors for all books that have been written by more than one author. Give the title column an alias of "Book Title" and the column showing the number of authors an alias of "Number of Authors". STEP 5: Back to top Using the BOOK_AUTHOR and AUTHOR tables for the upper most query, create a sub query that will return the BOOKID, and the first and last name of the author(s) who have written the book(s) that have been purchased the most. To successfully accomplish this, you will need to first find out the maximum total number of copies (based on quantity) sold of a book (based on bookid) in the ORDER_ITEMS table. This will be done in the bottom most query. The return from this query will be used to compare against the BOOKID in the ORDER_ITEMS table that occurs an equal number of times in the middle query. The return of this query will then be used to compare to a BOOKID related to an Author in the tables of the top most query. (HINT: Be careful, you will need both GROUP BY and HAVING clauses for your solution.) STEP 6: Back to top Using the correct tables, create a sub query using either join operation you wish that will list the customer number, first and last name concatenated together, and city for all customers who have placed an order for the most expensive book (based on retail price). Give the combined customer names column and alias of "Customer Name". STEP 7: Back to top Using the ORDER_ITEMS table, create a query using the correct functions to return the item#, the total quantity of items ordered with an alias of "Total", the average quantity per order with an alias of "Average" (since averages are often in decimals, only show two decimal places), the minimum quantity ordered with an alias of "Minimum", and the maximum quantity ordered with an alias of "Maximum". Your output results set should have five columns and four rows of data. STEP 8: Back to top Using the BOOKS table, create a query using the DECODE function that will display the book title, the published date, and the publisher name (this is where the decode function comes in). Give the publisher name column an alias of "Publisher Name", and order the publisher names in descending order. The publisher names used should be the same as those in the PUBLISHER table. DO NOT join to the Publisher table for this query. STEP 9: Back to top Using the PUBLISHER table, create a query that will return a line of output like the one below for each record in the table. Be sure to use the correct functions in the SELECT statement, so that your output looks like the example below. The contact person for Printing Is Us Publishing is Tommie Seymour. Be sure to use the correct function to display the publisher name and publisher contact with only the first letter of each word capitalized. STEP 10: Back to top Using the correct tables, create a query using the JOIN ON method to display a listing of all customers who have purchased more than two books. List the customer’s last name, the customer’s city and state, and the number of books they have purchased. Give the number purchased column and alias of "Number Purchased". STEP 11: Back to top Using only the BOOK table for the upper most statement, create a sub query that will update the retail price of all books published by PRINTING IS US by five percent (retail * 1.05). Remember, all you have is the publisher "name". Use the sub query to find the publisher ID. To verify your update, provide a select statement on the BOOKS table before your update statement, and then a second select on the BOOKS table after the update. Once you have verified the results, you can issue a ROLLBACK statement to return the data to the original state. STEP 12: Back to top Using the BOOK_CUSTOMER table, write a sub query that will return the names of those customers who were referred by the same individual who referred Jorge Perez. Do not display Jorge Perez’s name in the returned results (Hint: you should only have two customers displayed and the exclusion for Jorge Perez must be associated with the upper query). STEP 13: Back to top Using the BOOKS table, create a query using the correct functions to return the category name, total number books per category with a column alias of "Category Total", and the total cost of all the books per category with an alias of "Cost". Format the cost column using the correct function to show dollars and cents with a dollar sign. This is the end of Lab #6 Back to top]HTML

CIS 336 CIS336 Week 7 iLab 7 Devry University

L A B O V E R V I E W Scenario/Summary There is a lot more to a database than just tables and the data in them. A very important part of database security has to do with using and understanding Database Views. Being able to enhance the efficiency of the database tables by using additional indexes is also a very important aspect of database development. Finally, being able to create and use Database Sequences to automate some of the sequential processes in the database can not only save time but improve efficiency. In Lab 7, you will have a chance to work with all three of these areas. General Lab Information and Considerations This lab will utilize the same set of tables found in the script file (LeeBooks.SQL) that were used for Labs 4 through 6. Each query in the script file you will create, must be numbered (use either –1 or REM 1 comments for numbering) and in order. The SQL for the following exercises should be written using notepad and run in SQL*Plus. Read each problem carefully and follow the directions as stated. A Clean Script File: A script file is meant to be like a program. The file can be run every time the code needs to be executed without having to retype the code again each time. For this reason, it is important that there are no errors in the code inside the file. You can go back and forth between notepad and Oracle when creating your script file to check your queries and verify if they work or not. However, you do not want to create your final output file until after you have verified that everything in your script is correct by running it in its entirety at least once and viewing the output. Once this has been done, you can create your final output file, with echo on to create the document, you can turn in with your lab. Remember in using a Spool Session, you must type "SPOOL OFF" at the SQL> PROMPT after your Script stops spooling to capture all of your data! Lab Do's and Don't's Do Not include the LEEBOOKS.SQL as part of your lab script. Do use Notepad to write your query script file. Do Not write your queries in Word. Do test each query before moving on to the next. Do Not include extra queries for a problem unless the problem explicitly asks for more than one query. Do test your queries before creating your final output file. Do Not turn in a scrip file that has queries with errors. Do number each query using either --1 or REM 1 comment notation. Do Not start your query on the same line as the comment. Do remember to check your final output and script file for accuracy. Do Not turn in your lab without first checking your output file to verify that it is correct. Things to keep in mind: If you are not sure of the table names in your user schema, you can use the following select statement to list them. SELECT * FROM TAB; If you want to know the name of the columns in a particular table, you can use the following command to list them. DESC Making a script file containing a series of describe statements for each table and then spooling the output will give you a listing of all the tables with column names. Be sure to review and verify your final output when you are finished. Do Not assume anything. Write queries for each of the stated problems in the steps below that will return a result set of data to satisfy the requirements. When finished, your resulting output file should show both the query statement and result set for each query. Deliverables The deliverable for this lab will include: Your script file with the seven queries and oneexplanation in it. Be sure your name, course number, and lab number are in a comment area at the top of your file. An output file created using SET ECHO ON showing both the SQL code and the results. Be sure that you include your answer to question #3 as a comment in this file. Both documents are to be zipped into a single file before submitting to the iLabDropbox for Week 7. L A B S T E P S STEP 1: Create a simple view named CUST_VIEW using the book_customer table that will display the customer number, first and last name, and the state for every customer currently in the database. Now insert the following data into the book_customer TABLE using an INSERT statement. (Do not use the View for this insert.) CUSTOMERID - 1021, FIRSTNAME – EDWARD, LASTNAME – BLAKE, STATE – TX. Now query your view and display the new record. STEP 2: Create a complex view named CUST_ORDER that will list the customer number, last name, and state from the BOOK_CUSTOMER table, in addition to the order number and order date from the BOOK_ORDER table. Insert the following data into this view (use the view for the insert statement): CUSTOMERID - 1022, LASTNAME – smith, STATE – KS, ORDERID - 1021, and ORDERDATE – 10-OCT-2004. STEP 3: In your own words, explain why the insert statement for the view you created in Step 2 did not work. STEP 4: Create a sequence that can be used to assign a publisher ID number to a new publisher. Define the sequence to start with seven, increment by two, and stop at 1000. Name the sequence PUBNUM_SEQ. STEP 5: Insert two new publishers into the PUBLISHER table, one named Double Week with a contact name of Jennifer Close at 800-959-6321, and the second one named Specific House with a contact name of Freddie Farmore at 866-825-3200. Use your new sequence to create the PUBID for each record. Now, query your PUBLISHER table to see your two new records. STEP 6: Using a single query, query the PUBNUM_SEQ to determine what both the current sequence number is and the next sequence number will be. STEP 7: Create a unique index on the combined columns ORDERID and CUSTOMERID in the BOOK_ORDER table. Give the index a name of BOOK_ORDER_IDX. STEP 8: Determine how many objects you currently own in your schema by querying the USER_OBJECTS view in the Data Dictionary. Your result set should list the different object types that you find and include a count by object type.

CIS 336 CIS336: All iLabs Week 1 to Week 7: Devry University

CIS 336 CIS336: All iLabs Week 1 to Week 7: Devry University

CIS336 Week 3 Group Project Task 1 Data Model

Present a detailed data model for the project scenario. You can create your data model using Microsoft Visio, which you will have access to through iLab and Microsoft Excel, which comes with Microsoft Office. Other tools may be used as long as the output is legible and conforms to standard format. (i.e. I will not be able to grade the data model if I cannot tell what it is supposed to be!). Your data model should include a minimum of an ERD and metadata chart (data dictionary).
A key component to every task submission is the team responsibilities document. This document should outline the contributions that each member of the team made to completing the task deliverable. There is a sample document in the Doc Sharing tab that can be used, or each team can come up with their own design. As stated in the syllabus, although this is a team project, each member will also be graded on their involvement in the project. This assessment needs to be honest and accurate in describing the individual members’ activities for the task.
Deliverables for this task:
A completed Data Model to include: An ERD, showing all tables, related attributes, and the primary and foreign keys. This diagram must show both the relationship and cardinality of the relationship using accepted notation. A Data Dictionary (or meta data chart) showing a minimum of the table name, columns, data types, length, and constraints. Team member responsibilities document outlining contributions by team members to this deliverable.

CIS336 Week 4 Group Project Task 2

Task 2 - Logical Model (30 points)
Using the Oracle SQL*Plus editor, develop a database for MiniQuest based on your data model. The database should contain all the tables and attributes discussed in the project specifications. Be sure to use your data dictionary when creating your tables.
A key component to every task submission is the team responsibilities document. This document should outline the contributions that each member of the team made to completing the task deliverable. To submit this task, you need to create a file in notepad called TEAM_X_TASK2.TXT, where X is your team identifier. For example, Team A would name the file TEAM_A_TASK2.TXT. In this file, create a heading called CREATE STATEMENTS, and then develop the CREATE TABLE statements required to create your database tables. Be sure to include the DROP TABLE statements at the top of your file so that you can reuse the file. If you include the wording CASCADE CONSTRAINTS as part of each DROP TABLE statement, then the order of the DROP statements will not mater. For example, to drop a table named customer, you would state:
DROP TABLE CUSTOMER CASCADE CONSTRAINTS PURGE;
After testing and verifying that all of your create statements work, create a spooled output file with the SET ECHO ON session command set so that your code and the results will show.
Deliverables for this task:
Revisions of Task 1 (if any) based on feedback from your instructor. Task 2 comprised of the CREATE TABLE script file and the output file showing that it works. Team member responsibilities document outlining contributions by team members to this deliverable.

CIS336 Week 5 Group Project Task 3

Task 3 - Verification of Logical Model(45 points)
Develop the SQL statements to insert records into the database. You should ensure that the data in the database is sufficient to allow for each of the reports requested by Ms. Smith to be tested. You need to show a minimum of three insert queries for each database table that you have created. Some tables will obviously require more to ensure that all of the required data is in the database (i.e., the packages table, program table, etc). To submit this task, add a comment heading called INSERT STATEMENTS to your corrected SQL script from Task 2. Add your INSERT statements for each table after this heading. Keep in mind that you will need to insert data into the tables in the same order that the tables were created. This will minimize any integrity constraint errors you might encounter. Keep in mind also that any values being inserted into a field defined as a foreign key field must first exist in a previous table’s primary key field. Save the file as TEAM_X_TASK3.TXT, where X is your team identifier. After testing your statements to verify that your data will insert into your tables, create a spooled output file with the SET ECHO ON session command set for submitting.
Note – Although you are only required to have three records per table in most of your tables for this deliverable, you will need a considerable amount of data in your tables for the final project.
After testing and verifying that all of your create statements work, create a spooled output file with the SET ECHO ON session command set so that your code and the results will show.
Deliverables for this task:
Any revisions of task 2 based on feedback from your instructor. Task 3 comprised of the script file containing DROP TABLE, CREATE TABLE, and INSERT statements, and the output file showing that it works. Team member responsibilities document outlining contributions by team members to this deliverable.

CIS336 Week 6 Group Project Task 4

Task 4 - Verification of Transaction Processing (30 points)
Develop a query that will identify and mark inactive those customers that have bills overdue by more than 30 days (this can usually be done using a sub-query). Remember, you are only marking a customer as inactive, not actually deleting the customer record from the system.
To submit this task, create a heading called MODIFY STATEMENTS in your group project SQL script, and name the file TEAM_X_TASK4.TXT. This should be the same script that contains your DROP TABLE, CREATE TABLE, and INSERT statements. Once you have verified that your SQL statement or statements work, create a spooled output showing the results of your statements.
Deliverables for this task:
Any revisions of task 3 based on feedback from your instructor. Task 4 comprised of the complete script file (DROP, CREATE, INSERT, SELECT, and UPDATE statements) and the output file showing that it works. Team member responsibilities document outlining contributions by team member to this deliverable.

CIS336 Week 7 Group Project Task 5

Develop the queries to support each of the reports that are required by Ms. Smith. It is expected that the information returned by the queries is adequate to be used in the reporting process. Make sure your output contains enough information! The following is a recommendation and the MINIMUM amount of data you should have access to:
Customer Table: A minimum of 12 customers (this will allow several channels to have more than one customer selecting it as a favorite channel) Billing Table: Records to support the above customers Program Table: A minimum of 25 programs (your program guide should have enough programs for various channels to support the program guide report) Other tables: A sufficient amount of data to support the above when reports are run
Create a heading of REPORTING STATEMENTS as a comment at the bottom of your group project database script file. Add the six report queries to this area. In instances where you are asked to allow for user input, please specify an appropriate value based upon the data in your script. For example, Report 1 is a DATE driven report; therefore, you should use a single date in your WHERE clause to display the information. Task 5 is the final task for the project and is designed to demonstrate that you have adequately satisfied the requirements of the project. The following is what you are to submit for Task 5:
Report 1 – A list of the programs on all channels for a specific day showing the channel number, supplier, package, program name, rating code, and show time. This will be similar to a program guide, only not package specific. This is a date-driven report, therefore it should only display programs for a single date specified. Report 2 – A sample program guide showing the channel number, show time, program name, and rating description. For the purposes of this project, your report should be package ID specific (based on a given package ID) and you only need to demonstrate a single package ID. Your report should include all channels associated with the specified package. Report 3 – A list of all new customers signed up on a specific day. This should show enough details about the customer, including favorite channel, address, and minimal billing details. This report is to be date driven, so you will need to specify a date in your query. Report 4 – A list of all the customers made inactive on a specific date. This should show enough details about the customer to allow contact with the customer, the reason he or she was made inactive, and the user who made them inactive. Again, keep in mind that this is a date driven report. Report 5 – A list of each channel (both channel name and channel number) and a count of the number of customers who picked that channel as a favorite channel.
Report 6 – A summary of sales for any given day, categorized by package type (i.e., the total sales written on the specified day for each package subscribed to by customers, not bills paid). This report should give details about each package type, the package price, the number of packages sold, and then the total sales amount for that package. Once again, remember that this is going to be a date driven report.
