Hello Antonis,

No, those are not system tables: system tables are with RDB$ prefix.
Is there a chance that you used IB Expert to administrate your
database? If yes, probably IB Expert offered you creating of the
tables and you agreed with that. (IB Expert uses IBE$ tables for
audit, etc.)

AT> What can I do to not see them?
If those tables are of IB Expert (select from them to find out what
the data is there), you may drop them. I don't know about relations
between them (FKs, etc.), so I can't tell you the order of dropping -
you need to define it yourself.
