APQ is now a "generic" Ada95 binding to two databases:
- PostgreSQL
- MySQL
More to be added in the future.
The idea is that most of your application code can now
be made portable between databases. Only a bit of planning
and a change of one "with" and "use" statement is needed
in a main program to change database engines. An Ada95
application can also simultaneously work both types, if
you have a reason to do that.
A sneak peak of the APQ 2.0 manual is now available:
http://home.cogeco.ca/~ve3wwg/binding2.pdf
If you are interested in generic database programming,
turn to the chapter 8 "Generic Database Programming"
for an example of what the code looks like. This
chapter also discusses some areas of challenge WRT
to the different database engine personalities.
The binding software is undergoing final testing and
packaging, and will be made available soon. Check

for updates.
