I'm porting an application I made from VB6 to C++/Qt. In my original application, I didn't need an actual SQL server running, I could just use MS Access .mdb
files.
Does something similar exists for Qt that will work on multiple OSes? A database stored in a file, pretty much, but that I can still run SQL queries with.
I second the comment by "Mosg". Have a look at SQLite.
