摘要
在基于 CORBA的智能异构数据集成系统中 ,资源的不当使用一直影响着查询的效率和事务的处理。合理的利用系统资源 ,在很大程度上将提高系统的效率和安全。文章针对系统中数据的存储问题 ,引入数据仓库、语义缓存以及数据源连接池技术 ,通过重用系统中的历史资源和频繁使用的资源 ,为查询处理、事务处理等系统服务提供有力的支持 ,从而改善系统性能 。
In intelligent heterogeneous data integration system based on CORBA, utilization of resources has an impact on querying and transaction processing. Efficiency and security of the system is beneficial from reasonable utilization of resources. In this article, we devote our attention mainly to data storage and introduce some technologies including data warehouse, semantic caching and datasource connection pool. With reusing history and frequently accessed resources, the system will have good performance in querying and transactional processing service.
