Include all of the scripts in a single file called ITCO630_GP3.SQL.

Create at least three related tables in the database.

Create at least two stored procedures and a script to use each of them.

Create at least one view (using a script).

Create at least one trigger.

Create at least five useful queries. At least one of these queries should use a

subquery and at least one of the queries should use an aggregate function.

All scripts should be well documented.

Individual Summary:

In addition, you will prepare a summary document with the following information. This

document will be submitted as a separate item along with the ZIP of the database and

the associated files.

1. a Word document describing the system

2. an ERD or other graphical representation of the system

3. a description of the views, stored procedures, triggers, and queries

4. step-by-step instructions on how to run the queries that will demonstrate the

functionality of the system

5. a summary of strengths and weaknesses of the system, as designed

You will submit the database, log file, query files in a zip file called ITCO630_GP.ZIP,

and his or her own individual summary document as a separate submission. Please
