【摘要】 在三层结构中,中间层的实现是整个系统的核心。提出了一个基于消息中间件实现中间层的结构框架,能够以较少的花费实现一个分布式查询系统。中间层各个业务组件利用消息中间件通信,屏蔽了网络复杂性,实现异构平台的互操作,利用持久队列可以确保通信的可靠性,减轻了系统的开发工作和复杂度。更多还原

【Abstract】 An important requirement to develop 3-tier architecture systems is the construction of a reliable middle-tier with an effective way.Describe a middle-tier framework built on MOM (Message Oriented Middleware) to support a distributed query system. The MOM could provide a reliable message exchange mechanism for the query system to transfer high quantity data between business components. The development of systems could also be speed up because MOM could hide the heterogeneity of platforms and the complexity of network communications.更多还原
