首先描述了信息系统体系结构应具有的特征；提出了一种基于Ｉｎｔｒａｎｅｔ并能够对Ｎ 层Ｃ／Ｓ结构和Ｂ／Ｓ结构提供有效支持的企业信息系统体系结构；文章着重分析了支持该体系结构的３ 种关键技术：实现系统各构件之间相互通信同步和数据访问的构件标准，构件的开发和物理分布，以及数据（库）的设计和物理分布．
Firstly, the characteristics of information system architecture should be described. An enterprise information system architecture based on Intranet and providing effective support for N-level C / S structure and B / S structure is proposed. The article mainly analyzes the architecture of enterprise information system that supports this architecture The three key technologies are: component standards that enable synchronization and data access among components of the system, component development and physical distribution, and data (library) design and physical distribution.
