省级气象信息共享系统的中间件设计研究

Research of Middleware Design for Provincial Meteorological Data Sharing System

中间件技术屏蔽了底层分布式环境的复杂性和异构性,简化了分布式应用程序的开发,使分布式应用程序的健壮性、可扩展性、可应用性更好。本文通过对各类中间件特点分析和气象信息共享系统的需求分析,确定在气象信息共享系统三层架构中采用IBM WebSphere MQ消息中间件,并通过元数据导航功能实现共享系统中中间件服务器端和客户端的架构设计。

Middleware technology shields complexity and heterogeneity of underlying distributed environment, simplifies development of distributed application program, improves the robustness, expandability and applicability of DAP. This paper confirms the adoption of IBM WebSphere MQ message middleware by analyzing characteristics of various middlewares and demand of meteorological data sharing system, and realizes architecture design of server - side and client - side of middleware in sharing system by applying metadata navigation function.
