Two solutions come into my mind:
1. Do not inherit from DatabaseConnection, but pass a
DatabaseConnection object as a parameter to the FireBirdConnection's
__init__function. After this you can delegate the necessary
functionality to the DatabaseConnection (by using __getattr__). This
introduce
2. Maybe the layering of your application is wrong. If
DatabaseConnection provides common functionality to the different
Adapters, it should be on the same layer or one beneath the Adapters.
Another notice. If I put 'DatabaseConnection' under 'Adapters' then it
means that 'DatabaseConnection'
' under 'Adapters' then it means that 'DatabaseConnection' is an
adapter. But it is not. :-) In the other direction, Adapters are
deeper, so adapters should can DatabaseConnection-s (and in fact they
are).

I believe your response only applies to single inheritance. For classes
