远程教育技术规范XML文档关系数据库存储技术

Storing Distance Learning Technical Specifications XML Binding Documents Use RDBMS

针对在远程教育技术规范的XML绑定文档中,经常使用元素嵌套,强调数据的层次性、顺序性等特点,提出了一套基于Schema模式的将规范的XML绑定文档存储到关系数据库中的解决方案。该方案在存储文档时,通过建立元素表保存模式的信息,确保了元素的完整性,并在嵌套元素的数据表中添加Layer属性列,以表明元素的嵌套关系,保证了数据的有序性,避免数据在存储和恢复时产生混乱。对数据的存储做了详细的描述。

Distance learning technical specifications＇ XML binding documents often use nested elements, and emphasized the level and order of data, in allusion to the characteristics, put forwards a kind of XML binding document store in RDB method based on XML Schema. In this plan, establish an element table to save the schema information when store the documents. Then ensure the integrity of the element. And add layer property to the table of nested elements to show the relationship between the nested elements, and then ensure that the data ate order to avoid the data storage and recovery giving rise confusion. Has done a detailed description on data storage.
