Hi All,
I am going through ER diagram of a database and found out many tables are not related to each other.
I don't see any foreign key constraint to link the tables together.
I just wanted to know the best practices which are in the industry and wanted improve the current model. Is it okay to have tables without any such keys?
I used the Microsoft Database Diagram which is pretty good to use.
Also, I want to use the Erwin Community Edition and wanted to generate the full ER diagram based
on current database.
Any suggestions please!
Regards,
Prem
