>>Hi everybody, I want to begin developing a commercial application using VFP 9 as my front end and a free RDBMS (not DBFs) as the back end. I'd like to know what is the best one to work with VFP9. I have in mind 3: PostgreSQL, Firebird, and MySQL. I've never worked with them and of those three I guess MySQL is not completely free. I would like to know from the ones that have had any chance to work with any of those databases or perhaps any other that you may consider as a better alternative.

Thanks for the advice, but, I guess you have to pay for using Reporting service, right? I'm not sure about it.
