Yes, that can be done by writing an Ada binding to the C/C++ library.

That depents on the model. I do not know if there is COM support on
Sys V (I doubt it), but Corba should be doable.

Yes, its worth the effort, especially if you reuse the bindings for
other projects.

In that case (presuming there is no Ada binding to DBTools), why write
intermediate C or C++ code. Why not interface to the DBTools directly ?
