In your opinion, whats the db access library for C++ that is free (or freely available) and is fairly popular (most popolar??) and is object oriented and is fairly complaint to the stl? and yea, is available for windows and *nix's? :-)
If not available for windows. Only linux/unix will do.
I would look at a multi-platform GUI toolkit's implementation and use that. Something like QT or WxWidgets. They both have ODBC interfaces for multi-platform development.
Helios: They are multi-platform toolkits. Their functionality is centred around GUIs but they also provide multi-platform functionality for other things like networking, databases etc.
