Hello dear all,
I have some doubts regarding the use of users in Interbase.
Is it better if every user has its own id, or everyone can use a single user
like SYSDBA, for instance?
Then if it is better, how do I use create user, grant, revoke and so on
through a Delphi program?

What happens regarding the database performance?

Does someone has some example for sharing?
Or just some SQL example.

Thanks in advance.
Marcello
