Is database diagram in SQL Server Management Studio considered as ER diagram?

Question

I just have this simple question. in SQL Server Management Studio there is an option Database Diagrams, is it ER diagram ?

Answer 1

No I believe. ER diagram does not refer to relational data model and can be mapped into different data structures. SQL Server diagram is specific only to relational model and DBMS.

Answer 2

Yes, you can do a database diagram.

Expand DataBases --> choose database--> database diagrams --> right click(NEW DB diagram).
