Opening session in constructor is really bad thing Smile

I guess this is also because there will only be one DB session but possibly multiple instances of my app window, also performance.

The reson why it is bad thing is that if open fails, you will end with semiconstructed object...

I have lots of data that is currently in a spreadsheet. I will use php or perl to parse it out into a usable CSV or something similar. The actual structure of the DB can still be changed. The reason I did not opt for schemas was because I thought it might add a little extra (code size, memory usage) to the final product.

Only a little - and it is also possible to exculde that using #ifdef _DEBUG
