基于关系模式的XML数据存取技术研究

虽然新的数据库技术如面向对象数据库、XM L数据库等发展很快,但其技术还很不成熟,各领域的数据交换更加频繁,半结构化的数据大量产生,利用关系数据库的成熟技术对这些数据进行存储和处理显得尤其重要。本文介绍了如何实现XM L DTD到关系模式的转换,同时给出了从关系模式到XM L DTD的逆转换,这种转换保持了原XM L DTD的语义约束。

The relational schema-based Research on the Techniques of Storing XML Data

Although the new database techniques such as object database,XML database have been developed by leaps and bounds,these new techniques at present stage are still quite immature.While the frequency of changing different domain' datum is high and the quantity of producing semi-structure data is more,it is significant to store and process these datum using relation database techniques.This paper introduces the procedure of mapping a XML DTD to a relation schema.This mapping must capture the semantic constraints hidden in the given XML DTD.
