Hi !

Usually I try to guess about structure of databases and what it can be use for.
(Especially if it empty you will have weak hope that it will not use).
After that I try to find author. If it impossible, try do delete them and
test your project sometimes it requests a lot of time, but it depends...
In my personal practice I try to not delete any unknown tables or databases...
That is my rule... If it works do not delete anything.

Have a nice day!

>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?
