In these days, enterprises are more and more confronted to fast changing and turbulent markets. In order to remain competitive, they have to quickly adapt themselves to these new situations. The integration solutions employed in such an environment enable the required agility, by using a loose and flexible integration architecture. We propose an integration solution based on the concept of propagating data changes from one information system to the affected information systems. This paper focuses on the question: how data from other data services can be accessed and exploited to enhance a data change propagation system. These services are based on a service-oriented architecture (SOA) using XML technologies (e.g. SOAP). We developed the Data Service Description Language (DSDL) to define the data structures of the data service. This description is used to create the above mentioned Transformation Scripts as well as to generate requests for accessing remote data. A layered system approach is introduced to facilitate both the architecture and its implementation.
