Research Of Cooperative Database System Integration Technology Based On Agent

Computer Supported Cooperative Work is an interdisciplinary research field which combines the computer and communication technologies with collaborative approach of human groups. At present, CSCW has been widely used in many industries. The different units who use different types of databases separately may need to work together to improve the operational efficiency. In this case, it has now become important issues that in the cooperative environment how to ensure the integrity, consistency and safety of data, to access data from several independent, distributed, heterogeneous data sources and process data in different systems of hardware platforms, to show users by the way of unified and friendly, to achieve transparent access and interoperability among different systems.By analyzing the cooperative database architecture, the current integrated method of database system and the characteristics of database system, this article which was based on dwelling on the research background, theory technology of the subject and database system, cooperative database and agent technology, advanced the research programs of introducing agent technology into integrated system, and then built agent-based cooperative database system integration model. After analyzing the differences between coordination mechanisms and the operational mechanism of traditional database, this article advanced the countermeasures and solutions of agent communication mechanism, schema integration, query processing and optimization and transaction management mechanisms in the cooperative environment which were the collaborative mechanisms of cooperative database system.Finally, on the basis of above studies, this article designed and developed agent-based cooperative database integration system, implemented the primary agent module, secondary agent module and datasource interface agent module, and then conducted simulation testing of the integrated system in terms of the frequent operating efficiency, load balancing and so on.
