碩士 === 國立政治大學 === 資訊管理學系 === 90 === XML (eXtensible Markup Language) is the emerging data format for data processing on the Internet. XML provides a rich data semantics and data independence from the presentation. Thanks to these features, XML becomes a new data exchange standard and leads new storage and query processing issues on database research communities. In this paper, the performance evaluation issues on XML databases have been studied and a generic and requirement-driven XML workload model that is applicable to any application scenario or movable on various platforms is developed. There are three sub-models in this generic workload model, the XML data model, the query model, and the control model. The XML data model formulates the generic hierarchy structure of XML documents and supports a flexible document structure of the test database. The XML query model contains a flexible classical query module selector and an open query input to define the requirement-driven test query model to challenge the XML query processing ability of the XML database. The control model defines variables that are used to set up the implementation of a benchmark. This open, flexible, and systematic workload method permits users in various application domains to predicate or profile the performance of the XML database systems.
