"We are using Firebird SQL since 2003 for our shareware application. Most installations are single user for which we use the embedded engine, we also have some multi user installations which use a full server installation. Being able to develop one code base to be used for both i.e. "simple" single user setup and for a full server setup is a big plus for us. We had started with Firebird SQL version 1.5 and have later upgraded to 2.0, then to 2.1 and are currently using 2.5. In all these years with a few hundred installations we have never encountered any database related problems."
