Nowadays complex distributed applications are often built on top of autonomous functional entities called Web services. There exist various heterogeneous technological domains that Web services can belong to. The used protocols and programming models may differ vastly from the ones used in other domains. This fact poses a challenge to developers that want to create service compositions incorporating services from different technological domains. Developing such a composition requires knowledge about the involved data formats, protocols and other technology specific details of the involved services. This diploma thesis will firstly present a concept that provides a model for uniform interfaces for services stemming from heterogeneous technological domains and, secondly, a model that allows the creation of service compositions from heterogeneous services, utilizing the uniform interface. The concept will also provide means to handle heterogeneous data structures within a service composition and a runtime environment allowing the execution of composite applications which use the underlying data model.
