基于关系数据库的半结构化XML数据组织技术

摘要

There are many XML data organization and management technologies .XML data ,data schemata ,and semi-structu-red XML data features were described ,the XML database and XML data storage methods were introduced ,main XML data organiza-tion strategies in the relational database were discussed .The semi-structured XML encoding was divided into the order encoding , the path encoding ,the hybrid encoding and the update-supporting extend encoding based on the encoding mechanism .The semi-structured encoding technology was analyzed and summarized .The XML data organization technology development tendency was prospected ,and the foundation for further XML data organization technology research was provided .%XM L数据的组织和管理存在多种方法。描述XM L数据、模式以及半结构化XM L数据特点，介绍XM L数据库与XM L数据存储方法，讨论XM L数据在关系数据库中的组织策略；基于编码机制，将半结构化XM L 编码分成次序编码、路径编码、混合编码和支持更新的扩展编码，分析总结半结构化XM L数据编码技术，展望XM L数据组织技术的发展趋势，为进一步进行XM L数据组织技术研究提供基础。
