CIS336 CIS 336 CIS/336 iLab 7 of 7 - SQL Course
________________________________________
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…...

Most functions can be used in either the SELECT statement or the WHERE clause, but more commonly are used in the SELECT. Chapters 5 and 6 cover most all of the normal processing you use in these functions. In some cases, you will be asked to used more than one function within a single SELECT statement.

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. 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 #5 will explore all of these applications of the SELECT statement.

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......

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 The Clapham 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......

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......
