The systems analysis and design project that you choose for the INFO 2401 should meet the following requirements.

• The project should address a real life situation and be implementable (though you will stop with the design in this project). I suggest that you search the Internet for E-commerce systems that you can use. For example, the following are good sources:

airline (or train, cruise, concert, or other) ticket purchase

shopping sites on the internet

Online banks and financial institutions

Online insurance (life, medical, homeowner, and others) purchase

Rentals (car, video, audio, and others)

Auto teller Machine (ATM)

You can also use traditional firms if you can get the requisite permission from the appropriate people. Also, they should be able to provide you with the data to complete your project.

• For the firm you have chosen, identify the major functions that a visitor can perform on the website by navigating through the website. You may have to register at the site to get access to the more important functions the site allows you to perform.
• Document each function. Figure out the process used in each function, the inputs used, and the outputs generated. The contents of web pages that you see will give you information on these. However, web pages alone will be inadequate. You have to use your knowledge about the industry/firm/function to identify other data used by the system.
• Identify at least two problems or limitations related to the functionality. The limitations could be new functions that could be useful to a potential customer or improvements over existing functions. The problems not are related to aesthetics or speed of the website.
• Analyze the models and propose a new system.
• Transform the models into detailed design. The design should include
• A Context Diagram
• Entity-Relationship Diagram (ERD)

Data Flow Diagram (DFD)
