中文摘要: 利用中间件方式进行异构数据集成是异构数据集成研究的热点。针对目前中间件方式处理关系数据库数据与XML 数据集成在查询易用性以及效率的不足,基于各数据源的数据格式以及存储方式,把异构数据源分成关系数据库数据源,XML 数据源和非结构化数据源三类,对每一类用XML 模式处理,构建虚拟视图,使待集成的异构数据源构建成一个逻辑数据库。通过在中间件中引入XQuery 处理器,使其处理XML 数据和关系数据库数据并行,并结合SQL 语言以及JDBC 设计逻辑数据库操作语言及接口,为用户操作异构数据源提供统一的方法。在此基础之上设计并实现了异构数据集成中间件,通过模拟实验表明该中间件可以支持数据查询与更新操作,简单易用,扩展性较好。
Abstract:The research of heterogeneous data integration based on middleware is a hot research in this area. Considering the querying efficiency and the ease of use, classified the heterogeneous data source three types based on the data's format and saved method, using xml schema to rebuild each data source, construct a logic database. Take the XQuery processor as a part of middleware to process the xml data specially, then designed uniform interface to operate the data source refer to SQL and JDBC for the user. Based on this idea, designed and implemented a heterogeneous data integration middleware, the experiment showed that the middleware can deal with searching and updating data, with simple using and good expansibility.
