OroTimesheet uses Firebird

OroLogic uses firebird in their product OroTimesheet (Thanks for the tip pabloj)

Here is what they say about firebird 🙂

OroTimesheet 5 uses the database Firebird 1.5 to store its data. Firebird is a relational database that can be installed on Windows, Linux, Solaris and other platforms.

Using Firebird with OroTimesheet 5 gives users a great reliability and stability (relational database), a low licensing cost (Firebird is free, only OroTimesheet 5 licenses must be bought) without forgetting that Firebird can be installed on the platform of your choice (Windows, Linux, Solaris and more)
