摘要 结构化和半结构化数据的统一集成和访问是目前Web数据访问中急需解决的问题。文章提出了一种半结构化数据表示模型———层次数据图(HDG),给出了结构化数据向HDG的转换方法,并就不同结构HDG的统一集成问题进行了探究。 Integrating and accessing structured and semi-structured data by a unified way is an emergency question of Web data accessing.This paper presents a representing model for semi -structured data—— — Hierarchical Data Graph(HDG),proposes a method of transforming structured data into HDG,and inquires into the questions about integrating deferent structured HDG.
