一种异构数据库协同的解决方案

A Heterogeneous Database Collaborative Solutions

提出一种异构数据库协调的解决方案,该方案吸纳了数据库元数据、中间件、LDAP目录服务等思想。它采用CSCW体系结构中的联邦结构,对应用中输入的要求,在通信处理器的支持下,由协调控制器调用数据库元数据目录服务,协同查询处理、事务管理、完整性约束模块,访问底层数据库,较好地屏蔽了异构性,其中协调控制器以基于Agent的三层协作模型来实现,数据转换可以采用统一的数据转换格式XML文档,工作方式为多线程。

Presents a heterogeneous clatabase coordination solutions, this scheme absorbs a database metadata, middleware, LDAP directory service thought. It USES CSCW system structure of the federal structure, the application in of the input requirements, in communications processor, under the support of the controller by the coordinating call database metadata directory services, the collaborative query processing, business management, integrity module, visit the underlying database, better shielding the heterogeneous sex, including coord＇mation with the Agent based on controller three cooperation model to achieve, data transformation can use the same data transfer format XML documents, work method for multi - threading.
