ER Model

[GoogleCodeExporter]

Since our ER Model is still in beta mode, we should try to rectify all the 
discrepancies at the earliest. 

Current issues with the Model -

1. As we discussed earlier, the deadline attribute should be removed from the 
*selects* relationship and should be provided as a different entity - 
Configuration in relation with the entity - admin with attributes as status and 
deadline. Can we make deadline as a multi valued attribute as there would be so 
many deadline for different tasks? Any other entity is required?  

2. It was suggested to us that there should be a '3-way relationship' between - 
teaching_assistant, course, form. But since form is a weak entity, wouldn't it 
depend on course as well after the '3-way relationship'? Confused here. 
Suggestion? 

3. Some pieces in this ER model are still missing. Inputs, Suggestions?

We also need to find some way to show the Dual role of the Admin - TA 
Allocation In-charge as well as Instructor.
