数据资源系统架构设计

A Design of Data Resource System Architecture

本文描述了通用数据资源服务系统的架构设计。我们将不同资源分为数据库、文件、分类三种基本资源类型，并讨论了其抽象接口设计，然后讨论了此设计中的三层（数据层／逻辑层／表现层）体系结构划分及组件，最后简单描述了检索集群的设计。

This article describes the design of common data resource service system architecture. We classify different resources into three basic types, which are database fil and category. And we discuss the interface design of them. Then we discuss the three layered architecture （data layer, logic layer, presentation layer） and components in this design. At last we simply describe the design of search cluster.
