摘要
多数据源互操作与开放分布处理系统ＣＩＭＳ－ＭＩＯＤＰ是采用分布对象互操作与代理技术，实现面向ＣＩＭＳ的基于ＲＰＣ的远程对象访问ＲＯＡ（ＲｅｍｏｔｅＯｂｊｅｃｔＡｃｅｓ）功能和基于ＳＱＬ３的远程数据库访问ＲＤＡ（ＲｅｍｏｔＤａｔａｂａｓｅＡｃｅｓ）功能的系统，为ＣＩＭＳ环境下的信息集成与分布处理提供了不同层次的支持功能。本文讨论了ＣＩＭＳ－ＭＩＯＤＰ系统的主要设计和实现问题，包括基本模型、扩展服务和协议、对ＳＱＬ３的支持、系统实现结构等。
By adopting the techniques of distributed object interoperability and mechansim of object broker, CIMS-MIODP implements Remote Object Access(ROA)based on RPC and Remote Database Access(RDA)based on SQL3, and supports interoperability at the levels of database, respectively, for information integration and distributed processing in CIMS. This paper discusses main issues of design and implementation of the system, including the basic model, the extended services and protocol, the supports for SQL3, the system architecture and so on.
