[odb-users] How to build a schemaa with many .hxx files (one by class)

[Per Edin]

Hi David!

I assume by the directory name "tablas" that you are still thinking in
terms of tables.

Are you trying to map C++ objects to existing database tables?

If not, I would strongly recommend that you stop thinking in terms of
tables and just concentrate on your objects and object graphs. It will
make your life so much easier and is the whole point of an ORM system.

Best regards,

Per Edin
