基于COM+的分布式多层设计分析

Analysis of COM+ Multi-tier Construction

COM+Service是对WIN2000中COM(组件对象模型)的扩展,简化了程序设计过程中组件的创建和使用过程,同时也提高了程序的可剥离性和设计的灵活性。它与WIN2000Server的结合为用户设计分布式应用程序提供了一个复杂精密的架构。本文从层次转化、代码隔离、面向WEB等几个方面对多层次的设计思想进行了详细说明。

Integrated into Windows 2000,COM+ Service extends the COM (Computer Object Model) to simplify the creation and use of software components, while improving application scalability and flexibility. Integrited into WIN2000 Server. It afford a intricate infrastructure for building distributed applications. This article gived a detailed discription on the idea of multi-tier construction ,from the following aspects: tier changing ,code segregation and so on.
