Hopefully I'm able to articulate this well: I am porting a credit card applicatoin I made years back from VB6 (I understand, I understand!) to C++/Qt. During my original application, one factor I loved was which i did not need a real SQL server running, I possibly could only use MS Access .mdb files. I'm wondering if such like is available for Qt which will focus on multiple OSes - a database saved inside a file, virtually, but will be able to still run SQL queries with. Unsure if something similar to this is available or otherwise, but any help appreciated, thanks!
