hello everyone,

I need to study a system that is written by some old programmers in my company, it has a large set of database. However, some free tables are actually not needed by the system anymore but still in the package. What I need to do is to find them out and delete them, is there any efficient way to find out which database is used by the system and which is not? is there even any tools to do it?

Thank you very much!
Jimi
