| 摘 要： | 分析了基于关系数据库的XML数据存储现状,阐明了树结构XML数据模型与平面结构关系数据模型之间的不匹配性,在此基础上对存储粒度进行了研究,着重分析了细粒度模型的原理.使用Java实现了一个XML关系存储系统,用于管理和操作XML数据,讨论了采用细粒度模型存储XML数据的具体实现流程,项目的实施表明,相对于中粒度和粗粒度,细粒度方法使XML数据操作变得灵活方便.

| Abstract: | The situation of storing XML in relation database is first presented and the incompatibility of the plane-structure-based rela-tional data models with the tree-structure-based XML data model is illustrated.On this basis,a study on storage granularity is done by focusing on the principles of fine granularity.A XML relational storage system is implemented through Java to manage and operate XML data and the specific implementations of XML data storage through fine granularity are illustrated.Finally,the projec... |
