Thanks for your reply Yusef.
I am actually creating an ERD for authenticating the user when he logs into the database. So I will need a set of tables to identify if user exis and password is correct.
After this some tables will exist for checking his department, his group. On the basis of his group he will be able to access only relevant parts of application. Its like a role or a privelege thing.
Please tell me if the database tables that I have identified are correct ? Please ask questions so I may get to the best solution please.
Thanks
