abstract: 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)
