摘要
该文提出了一种基于组件技术的三层C/S结构的分布式联邦数据库模式,用来管理和实现分布式异构数据库信息集成和数据访问,将系统功能模块封装到组件中并放在中间层的应用服务器上,使得此异构系统具有良好的可重构性。并以PowerBuilder9.0为开发工具、EAServer的JaguarCTS为应用服务器实现了一个基于仿真系统的异构数据库通用集成环境。
This paper gives out a kind of method in designing three - tiered client/server Heterogeneous Multi - Database Accessing Based on Component Technology, and, uses this method to administrate and realize information integrating and data accessing of distributed - Heterogeneous - Multi - Database, encapsulate the system function＇s modules and send them to application server, and make the Heterogeneous system have good recomposation. It also develops a Heterogeneous - Multi - Database＇s Universal Integrative Environment based on simulation systems by using PowerBuilder 8.0 as developing tools and EAServer as application server.
