I have a few very basic queries.

I am learning to use FireBird from VB.

I am currently using Oracle for all my database requirements. I want
to swtich to FB.

Here are a few of my requirements.

Once logged in as Administator

1. how can we get list of users currently logged in?
2. how can we get list of all the database registered with FB?
3. how can we get list of all the tables in a particular database?
4. how can we get list of all the fields in a particular table?

I am seeing FBManagerLite do this, but it is developed in Delphi. Can
we do it ?

Thanks in Advance.
