摘要
学科知识库是一种内容管理系统,其中包含大量半结构和非结构化信息,对数据模型和数据库设计方法提出了新的要求.文中分析了学科知识库中的主要对象及对象之间的复杂联系,提出了学科知识库的概念模式和逻辑模式,并分别用面向对象模型和XM L Schem a来描述.这两类模式能帮助认识学科知识库的内涵.
Discipline Knowledge Repository （DKR）, which includes semi-structured and un-structured information and belongs to Content Management System, asks new requirements for the data model and the modeling methods. In this paper, an object oriented model and the corresponding XML schemes are proposed, which respectively specify the conceptual scheme and the logical schemes of the DKR. All kinds of classes and the relationships are analyzed in OOM, and the elements of XML schemes are described particularly. The two schemes help us to understand the structure of discipline knowledge, and are the foundation for building practical DKR.
