The continuous progress in communication, networking and database systems demands a new perception of data processing. A growing amount of network-based applications requires access to a multitude of mostly autonomous data sources located in a heterogenous software and hardware environment. Advances in database design offer new possibilities for the integration of autonomous local database systems. Active component systems do not only provide access to stored data, but significantly control business rules and integrity constraints by working cooperatively with each other while retaining the greatest possible extent of local autonomy. We introduce ideas and concepts for the realisation of active multidatabases by extending standard database interfaces.
