一种基于COM+的中间件平台的研究与设计

Research and Device of a Middleware Platform Base on COM Plus

传统基于COM+的三层架构开发模式在可重用性、可维护性和可集成性方面存在不足。文章以实现层与层之间的松耦合为出发点,将中间件平台技术引入传统的三层架构,设计并实现了一种基于COM+组件技术的中间件平台,为业务逻辑的定义、实现与运行提供了统一的规范和环境,为复杂应用软件提供集成框架,同时支持统一数据访问、灵活实现业务处理过程,为三层架构软件的开发、运行提供了支撑环境。并与传统的开发模式进行了分析、比较,验证了本平台的有效性。

Traditional development mode of three-tier architecture based on COM plus has defects in reusing, maintaining and integration. This paper starts with achieving the weak coupling of tier to tier in three-tier architecture, combines middleware platform with three-tier architecture, designs and achieves a middleware platform based on COM plus, provides a united norm and environment for the defining, achievement , execution of business logic, provides an integrated frame for involved application, supports united data access and flexible achievement of business logic, provides a supporting environment for development and execution of three-tier architecture software. At the same time, the paper analyses and compares with traditional development mode, which shows good performance of this middleware platform.
