This is not a database dump file. This is an actual database file. Absolute Database is a file based database, kind of like a proprietary version of SQLite. The client accesses database tables by directly opening the database file on disk or on a network share for multi user access. You do this using a Delphi component set produced by ComponentAce.
As far as I know there are no libraries for accessing Absolute Database other than ComponentAce's own Delphi components. Googling I found a ten year old post about an ODBC driver -
I don't think this driver is maintained anymore though.
There is a free for personal use version of the Absolute Database components which comes without source code, but it still requires you to use Embarcaderos Delphi or C++Builder development environment.
Your best bet, I think, is to contact the ComponentAce company directly and ask them if they have any options for you.
