Powerfull and easy to use RDBMS. I use it since version 1.03.
Even when we are trying to incorporate Firebird in our application development, we have had several problems with .Net Provider and/or DDEX. I know Firebird is made with a huge effort of many professionals for free. But there are guys like Jiri Cincura who does not accept input, he even has his own bug tracker and can erase cases easly when he looks uncomfortable. So there must be some way to complain about this kind of guys in order to avoid that behavior and, moreover, to have some fair way to control bug tracking. I am going to get more and more involved in Firebird project to know exactly how this is maintained and help in the developing effort too.
There are no 2 star reviews.
