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.
