摘要
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、可用性更好。介绍了面向对象中间件、面向消息中间件、面向大规模分布式系统中间件、服务质量中间件等当前各种中间件技术发展的现状,分析了中间件技术的原理、种类及在地震信息系统中的应用,提出了中间件技术研究的几个发展趋势,即网格技术、面向移动计算、面向服务质量等。
Middleware technique can shield the complexity and heterogeneity of a distributed environment of bottom layer,simplifying the development of distributed application and also making the robustness,extensibility and availability better.In this paper,current development of object oriented middleware,message oriented middleware,large scale distributed system oriented middleware and middleware for quality of service etc.are introduced.Also, principle,type and application in earthquake information system of middleware are analyzed.Some developing trends in middleware technology,such as grid technology,mobile computation oriented technology and service quality oriented technology are discussed.
