基于CORBA的规划推演系统数据服务的设计与实现

Design and implementation of data service in plan simulation system based on CORBA

以大型活动规划推演系统开发为背景,针对分布式系统中数据通信、数据访问和处理的实际需求,基于目前主流对象中间件技术(CORBA),设计了数据服务和数据访问客户端的体系结构,利用UML类图和顺序图描述各功能模块的工作原理和流程,借助Delphi构件化开发环境,实现了数据服务及其访问客户端。

To develop a plan simulation system for large-scale social activities, the requirements on communication, data access and processing in this distributed system were discussed. Based on mainstream middleware technology （CORBA）, the authors designed the communication architecture between the c/ient and the server, introduced the mechanism and flow of the modules with UML class diagrams and sequence diagrams, then implemented the data service and data access client on Delphi platform.
