Oracle XML DB和DB2 pure XML在XML文档存储查询性能方面的比较分析

COMPARING AND ANALYZING ORACLE XML DB AND DB2 PURE XML ON XML DOCUMENT STORAGE AND RETRIEVAL PERFORMANCE

可扩展标注语言XML在计算机软件的数据接口定义中有着广泛的应用。分析Oracle XML DB和DB2 pure XML关于存储和查询XML文档的技术特点及其实现原理,并通过测试比较,分析这两种技术在存储和查询效率上的差异。在相同XML文档存储负荷下,Oracle XML DB与DB2 pure XML关于存储和查询的耗时之比分别约为2∶1和1.32∶1。

XML,or eXtensible Markup Language,is widely applied to data interface definitions in computer software.The article analyzes the technical characteristics and implementation principles of Oracle XML DB and DB2 pure XML about storing and retrieving XML documents.Through tests and comparison,the efficiency difference on storage and retrieval between the two techniques is analyzed.Under the same XML document storage burden,the time consuming ratio between Oracle XML DB and DB2 pure XML about storage is roughly 2∶1 while that about retrieval is roughly 1.32∶1.
