Most enterprises have a diverse environment of heterogeneous and
autonomous information systems. If the same data is relevant for
several information systems, then data changes in one supplier
system affect data stored in other demander systems. The process of
exchanging changed data between systems, named change propagation,
is based on dependencies established between these systems. The
management of a single, integrated enterprise information system is
often infeasible or too expensive, due to the autonomy of business
units and the heterogeneity of their IT infrastructures. The
solution is to support the enterprise by a generic approach able to
manage data dependencies and to transform data stored in a source
information system into data stored in the dependent information
systems. We propose a loosely coupled system, called Stuttgart
Information and Exploration System. Our prototype mainly consists of
a data dependency specification tool, a propagation engine and a
repository that stores all relevant objects for these components.
