摘要
本文给出了ＣＩＭＳ环境下的实现应用系统、多种数据源互操作与开放式分布处理（ＯＤＰ）系统的实现机制、方法和原型系统。提出了基于数据库远程访问（ＲＤＡ）、数据库远程调用（ＤＢＲＰＣ）规范的ＯＤＰ层次模型；给出了实现ＲＤＡ、ＤＢＲＰＣ的多数据源互操作客户／服务代理机制与实现结构，ＲＤＡ／ＤＢＲＰＣ数据通信服务器互连机制，语言接口和应用编程接口。
This paper presents the implementation mechanism, method and prototype system of ODP(Open Distributed Processing) system, as well as the implementa tion of the interoperation between the application systems and multiple data sources in CIMS. Based on RDA (Remote Database Access) and DBRPC (Database Remote Procedure Call) specifications,a hierarchical model of ODP is also provided. In the end, the Client/Server agent mechanism and implementation architecture of accomplishing the interoperation among multiple data sources of RDA and DBRPC, the interconnection mechanism of RDA/DBRPC data communication server, language interface and application program interface are fully discussed.
