摘要
研究了基于中间件的多层次体系结构在大坝管理信息系统中的应用,通过分析系统表现层、逻辑业务层和数据层的构成和功能,开发了逻辑业务层的核心中间件应用层总线和针对分布式异构数据库的通用数据库访问中间件,从而解决业务功能统一管理的问题和数据分布存储与应用集中的矛盾,以实例表明了中间件将在新一代DMIS中发挥更重要作用。
A feasible architecture of dam management information system can not only shorten the development period, but also improve the stability of the system. The applied middleware technology can not only support heterogeneous-platforrn＇and distributed systems, but also balance resource and has the advantage of code reusing. It has been used in multiply-layer Client/Sever System as each layer frame or the relationship between layers. This paper has researched the application of middleware in dam management information system based on multiply-layer architecture, analyzed the structure and function of the presentation layer, the logic service layers and the data layer, developed the core middleware of the logic service layers-service layer bus and the general database access middleware aiming at distributed heterogeneous databases, solved the unified services management problem and the contradictions between distributed data and centralized application.
