Enterprise Information Systems (EISs) are built in isolated and independent environments leading to unpredictable and incompatible structure of data stores. An EI system can expose its functionalities as Web services to share resources of existing global internet infrastructure. The goal of this research paper is to facilitate inter-operation between Web services. Successful and reliable information (message) exchange between Web services is necessary to meet the current challenge of Enterprise Information Integration (EII). A real- world business process, which consists of Web services WS1 and WS2, can be used as a practical scenario for data or message exchange between Web services. In this scenario, message is exchanged by using output of WS1 as input of WS2. If data format of WS1 and WS2 are heterogeneous or incompatible, interoperation between them is impossible if data mediation is not used to resolve message level conflict and incompatibility in the context of syntax and semantics. Data Mediation requires mapping a message from one format to another. We propose to derive a mediation technique that will enable previously less inter-operative heterogeneous Web services to become more inter-operative now. To improve inter-operational performance between Web services our data mediation approach extends and utilizes existing Web service supporting tools WSDL and SAWSDL. (Authors' abstract)
