摘要/Abstract

摘要： 研究了局部数据库中上推数据的内容、获取和描述,定义出描述局部数据库中上推数据的XML模式,作为集成机和局部数据库上推代理之间的通信规范,以此为基础实现中间件中的上推机.

关键词: 多数据库中间件；局部数据库上推描述；可扩展标记语言；

Abstract: This paper analyzes the content,extraction and description of the up-pushed data in local database.It defines the XML schema ofthe up-pushed data description in local database by DTD which is used as the up-push rules and communication standard between the agent of local database and the integrator.Based on it the up-pusher is realized.

Key words: multi-database middleware； local database up-push description； XML；
