A Study on Self-adaptive Heterogeneous Data Integration Systems

Along with thc rapid development of Internet and the extensive use of information technology in various fields, large amount of heterogeneous data has been produced. Tbe way of integrating these heterogeneous data has been a hot issue. In this paper, from the problems which enterprise information integration faced, a framework of self-adaptive heterogeneous data integration system (AHDIS) has becn given, and by using ontology, semantic similarity, web service and XML techniques, a self-adapted heterogeneous data integration platform which can be dynamically regulated has been built up successfully. With !his integrated platform, the global data model can automatically 'or semiautomatically be adjusted while a change has been made to the local data model, so that it can realize the data sharing among heterogeneous data sources.
