Quick Overview

CMIS 420 Project 2 Advanced Relational Database Concepts and Applications

1. Description:
Demonstrate your knowledge of PL/SQL programming by writing and thoroughly testing triggers and stored procedures associated with an e-commerce application that provides security logs for all transactions by user, product, and date. I will provide specific requirements and design details for this project below and we could have more discussion about the project in the Conferences area. Submit the scripts with all of your function SQL and PL/SQL code, and provide the results of running your scripts with the SQL*Plus spool command.

2. Functional requirement:
We will develop a small online transaction application supported by our database, movie distributing and renting system. In the application, we should meet three functional requirements:
1) Track transaction events, and track runtime errors.
2) Handle either movie distributing business process.
3) Application interface which allows users to process either orders.
4) No additional database tables are required unless you think it is necessary to enhance your application.

3. Track transaction events, and track runtime errors:
The link below provides a script which allow you to create two tables for tracking purposes One table for tracking events and the other for errors.
Script to create logs tables
Track errors or exceptions during runtime.
Track any error or exception occurs during your application execution. this means that you should include tracking code in every program unit you develop.
Take a look of the table for error logging and see what data should be inserted into the table when error occurs. The code should be part of error handling in exception handle section.
Track event or application process during runtime.
This type of logs for recording the events during the code execution. Content of the log may contain part of the data being changed and who changed it. The code to track events should be located at the end of a process.
Take a look of the table for event logging and see what data should be inserted into these tables after event occurs.

4. Handle movie distributing business process.
In this part of the project, you are asked to design a few stored procedure or functions to handle online movie distribution.
These procedures or functions should be able to
1)process orders for distributors. When a customer (movie store) places order, ordering information should be stored in database tables.
2)allow customers (movie stores) to check movie availability. if it is available, provide number in stock and unit price. If unavailable message the customer the movie requested is not available.
3) if the order has been filled, generate an invoice to send to the customer.
Note: This is one of the place where tracking event is necessary.
Errors and events should be both tracked as described before.

5. Application interface which allows users to process either orders:
In general, the interface should provide GUI to users. However, PL/SQL does not have that feature. What we are going to do is to develop script which performs the similar functionality.
Script should be able to
1) take an order (ordering data)
2) place an order by calling all the procedures used to process order.
3) generate and print invoice based on order id.
4) query event_logs and error_logs to show the result of the order transaction and/or any potential issues within the order.

6. Submit requirement:
The scripts to create procedures and function.
The script to execute the procedures to place orders
The text file for output of execution results.
