I have a big app, implemented in Delphi 7. The DBMS is MS SQLServer.
Well, we want to develop a few modules to browser and a few using
multi-tier (because some modules should be a Desktop app by having to
communicate with some peripheral).
To this app, the server would be Windows. The modules from Desktop
too. But, in the future, I want to use Linux too.

New apps, I can use PostgreSQL so, no problems with drive connections.

I never use ODBC/FreeTDS on Linux. This is stable? All resources have
been implemented like SP's, multi-SQL in the same instruction, etc?
