摘要 半结构数据的模型是对半结构数据进行有效管理的基础,也是基于XML半结构数据管理系统的基础。首先探讨了半结构数据的表示形式;然后对XML数据模型进行了研究;最后,在以上研究的基础上实现了一种基于XML的半结构数据模型。 An appropriate data model for XMLbased semistructured data is required before a DBMS can be built. In this paper we first discuss the description of semistructured data and then we propose an extensible XMLbased semistructured data model for capturing and querying metadata properties, and the mappings for XML data to this new data model is also presented. 
