[boost] Re: VDB framework, possible submission?

Hello, Martijn,

I'm interested--hopefully someone else will be :-)

A question that I have is how generic is it?  I assume that the "virtual" in
the title should tell me that, but how would you plug a specific technology
to it, e.g., DAO, OLE DB, JDBC?  Or do I have to fill it up manually?

DTL is something that I've been exploring--still reading about it for ODBC.
It offers iterators over an ODBC source, filters and other niceties.

The Database Template Library:

Regards,

Javier
