Due to the demand of customization and the trend of globalization, enterprises are required to integrate value-added activities and resources across enterprises through enterprise alliance to quickly response the market changes and customers’ demand.”Virtual Enterprise” is consequently regraded as the most promising business model in the 21st century.

Information technologies are widely used in virtual enterprise. However, due to system heterogeneity, enterprise integration becomes a key factor for the success of Virtual Enterprise. Enterprise integration mainly includes three steps:Information Integration, Application Integration and Process Integration. Information integration is the fundamental construction of enterprise integration,due to it will affect application integration,process integration and the effectiveness of Virtual Enterprise.

In this study, the analysis and design of the information integration platform’s function modules and software components are first presented based on the characteristics and operational model of virtual enterprise and current information integration framework. Subsequently, the design of metadata and the development of the approach for metadata construction are conducted according to the characteristics of ontology. In this study, the uses of ontology matching and the technology of semantic similarity comparasion are employed to solve the problem of semantic heterogeneity and information variation.

Then, the design of core software using object-oriented method is presented. Finally, Java and web service are employed to develop software components, that makes software components have characteristics of distributability and integratability across platforms.
