Salam,
Attached you will find the definition for homework 3.
In this homework you will perform structured analysis.
You should create the context diagram, and then proceed to create level-1, 2, (and more, if needed) DFDs.
At the same time, you should create an ERD model.
System level behavioral modeling must be done through creation of state charts.
Also a Data Dictionary must be created, to check for consistency.
Please don't forget that this is the analysis phase, and you should only address the "WHAT", not the
"HOW".
Once again I plea that you only submit one single pdf file, with the correct mail subject, before the designated deadline.
Good luck.
--Regards,
Darioush
