Integration of information systems is the basic activity of 3 GEN. We provide methods, techniques and tools for linking and harmonization of user programs and data in order to secure comprehensive and integrated information systems. We are experts in a variety of operating systems (z/OS, Solaris, Linux, Windows), database management systems (Oracle, DB2, MySQL) and application servers (CICS, Oracle Weblogic, IBM WebSphere, JBoss). Accordingly, we can link heterogeneous information systems into a whole.
