Within many of our products the commitment to Open Source resulted in a high cost reduction and an increased efficiency in development as well as in daily use. 

Inside complex projects we emphasize on using Open Source products running on multiple platforms because mostly only these are capable of simple and flexible adaption.

In development environments our main experience is withhin PHP, Java, C++ and Smalltalk.

As Open Source databases we are usually using MySQL, Postgres and Apache Derby / IBM Cloudscape.
