XBench - A Family of Benchmarks for XML DBMSs

XML is beginning to be extensively used in various application domains, and as a result, large amounts of XML documents are being generated. Researchers in both industry and academia have proposed a number of approaches to e#ciently store, manipulate, and retrieve XML documents. The individual performance characteristics of these approaches as well as the relative performance of various systems is an ongoing concern. The range of XML application and the XML data that they manage are quite varied and no one database schema and workload can properly capture this variety. We propose a family of XML benchmarks, collectively call XBench, to measure and evaluate the performance of di#erent approaches to deal with the management of XML documents. The family is defined according to a classification of applications, and each class has its own database and workload. We discuss the general requirements for an XML DBMS benchmark, followed by a detailed explanation of the XBench, including the methodology of database generation, the workload, and the setup of test environment. A brief discussion of other existing XML benchmarks and comparison among them will be given as well. Contents
