Question

How do you use an ER diagram to analyze a system? The system must start with the first alphabet of your name (all attributes, occurrences, and relationships must be clearly explained).

Answer 1

Every object is an entity, and I think it shows the relations in the env.

The Entity Student is/going to be a Table in DB say Students

Ant the Relations may given to a LDS diagram, and can be Lessons, Semesters e.t.c., that are also Tables in DB.
