Kurzfassung

Flexible methods supporting the data interchange between autonomous information systems are important for today's increasingly heterogeneous enterprise IT infrastructures. Updates, insertions, and deletions of data objects in autonomous information systems often have to trigger data changes in other autonomous systems, even if the distributed systems are not integrated into a global schema. We suggest a solution to this problem based on the propagation and transformation of data using several XML technologies. Our prototype manages dependencies between the schemas of distributed data sources and allows to define and process arbitrary actions on changed data by manipulating all dependent data sources. The prototype comprises a propagation engine that interprets scripts based on a workflow specification language, a data dependency specification tool, a system administration tool, and a repository that stores all relevant information for these tools.
