Research And Implementation Of Agent Wrapper Model In System Integration

In information system field, the information systems to be integrated have the characteristics of geographical dispersion, entity heterogeneity and interaction among the demand lexibility of member. Components of the system can form a unified interface, which can solve the heterogeneity problem of the system. And using Agent technology can improve flexibility and collaborative of the systems. Based on above, using the advantages of the Agent and the components, this paper presents an Agent wrapper model which realizes systems integration.This thesis introduces the principle of the system integration and wrapper technology, and makes a study of technique and methods of wrapper systems in the system integration. Then we present the Agent wrapper model oriented the field of the system integration, which can be developed simply and quickly. The model has three layers with bottom-up design, including a function layer, a function Agent layer and a service Agent layer. The function layer forms a unified interface with COM technology and Python technology, which solve the heterogeneity problem of the system. At the same time, Agent of the function layer can expand reactive, autonomous and collaborative of Agent, which forms the function Agent layer. It provides a unified interface based XML information. The service Agent layer, which studies the Federalism thinking, has the characteristics of the function layer. And besides, it organizes the interactive relationship among the function Agents, which provides larger size of the service for external collaboration.Finally, this paper chooses a representative system in information system as testing case, and conducts the system integration experiment based on Agent wrapper model, which validates the validity and feasibility of the Agent wrapper model.
