The necessary specialisation in information processing in the telecommunication sector led to a wide range of software systems in the relevant software market. This can be traced back by the fact that there is a lack of capable and integrated solutions. If a telecommunication company comes to the decision to use specialised software systems, it has to face the sophisticated challenge of systems integration. This can be done at least at the levels of data, applications and processes. Illustrated by examples from the heterogeneous system environment at the telecommunication company EWE TEL, concepts for system integration and gained experiences are presented in this article. The following aspects are discussed in detail: integration of data by means of middleware, integration of applications using application server technology, and integration of processes by employing workflow management systems.
