模式映射弱依赖的XQuery到SQL转换算法

Xquery-to-SQL Translation with Little Dependence on Schema Mapping between XML and RDB

摘要: 通过提出并建立GVRS模型,作为XML视图与底层RDB之间的桥梁,实现了模式映射弱依赖的XQuery到SQL的转换算法.该算法降低了动态检索对静态模式映射的依赖性,可有效地避免因现有算法依赖性而导致的不同供应商之间的技术协调失败问题.

Abstract: A general virtual relational schema（GVRS） model is set up to serve as the bridge between XML instance document and factual RDB.The proposed algorithm reduces the dependence of dynamic query on static schema mapping,so the general adaptability of dynamic query is ensured.
