Hi
I have a design question and wondering how the best way to model it relationally.
You have a system which check's to see if a user can access it from 2 tables, say student and lecturer.
Is there a way to combine the access (Log-in) information in one table without replicating data that is stored in the student/lecturer tables?
Is there a name to this problem?
