内容知识库数据模型研究

Research of Content Repository Data Model

在Web应用环境下,如何有效管理大量的非结构化数据(也称内容数据)成为应用的重点。内容知识库作为内容管理系统的底层架构,不仅为内容管理提供了统一管理异构数据的平台支持,还为内容管理平台提供了更强的鲁棒性、移植性和通用性。当前的内容知识库模型基本都是采取关系数据库和分布式文件系统相结合的方式,系统功能较差,直接影响了内容管理系统的发展和应用前景。通过对已有非结构化数据管理模型的研究,提出和论证了新的内容知识库模型及其表达能力。不仅为当前内容知识库的建立提供模型支持,也为以后的工作指明了方向。

In the environment of Web application, it＇s very important to manage mass unstructured data（content data）. Content repository,as the underlying structure of CMS, provides the uniform platform supporting to manage inhomogeneous data,and makes the system more robust, portable and universal. Current content repository model adopts the structure that combine the relation database and distributed filesystem together, which is powerless to afford the development of CMS, Through research of the known unstructured data management model, a new content repository model is promoted and demonstrated. So,model supporting for current content repository building and future research is established.
