PROJECT PHASE I GUIDELINE

You can use the solution for Summer 07 CS4400 Project as an example how to make the solutions for ER Diagram (ER) and Information Flow Diagram (IFD).

ER-Diagram: besides the number of entitties, attributes and primary/partial keys, the score for this diagram is also based on if you can identify the weak entities, the identifying relationships, the cardinalities and the total participations correctly.

IFD: Every GUI in the project description that accesses the database must correspond to a task in the IFD. You can either group the similar tasks into one task and then have another diagram that shows the decomposion of the task or have all tasks shown in the IFD. The direction of the information flow arrows should be shown correctly. Below is the summary on the directions of the information flow.

Task: 
To update the database: an arrow from the task to the database
To query the database:  an arrow from the database to the task

Document:
To input data: an arrow from the document to the task
To display information: an arrow from the task to the document
