Abstract
With XML becoming a standard for representing semi-structured documents on the web and a standard for data exchange between different systems, some database companies are adding XML support to their existing database systems, while some other companies coming out with pure or native database systems for XML. In this paper, we present an experimental study on the query processing efficiency of a native-XML database system and an XMLenabled database system on a selected set of queries including operations from text-processing, DML and relation algebra. The experiments are conducted on two well-known commercial database systems using the web interfaces based on HTTP. The cost metrics we used are CPU time, the numbers of physical and logical reads. The queries were run on identical machines for 3 different sizes of documents with and without indexing. A subset of experimental results is presented and overall results are discussed. Generally speaking the XML-enabled system performed better.
