Abstract: XML support is being added to existing database management systems (DBMSs) and native XML systems are being developed both in industry and in academia. The individual performance characteristics of these approaches as well as the relative performance of various systems is an ongoing concern. In this paper we discuss the XBench XML benchmark and report on the relative performance of various DBMSs. XBench is a family of XML benchmarks which recognizes that the XML data that DBMSs manage are quite varied and no one database schema and workload can properly capture this variety. Thus, the members of this benchmark family have been defined for capturing diverse application domains.

Abstract: This paper summarizes the XBench family of benchmarks that are under development at the University of Waterloo. The benchmark identifies various classes of XML databases and applications and proposes a set of benchmarks to accommodate these classes.

XBench is a family of XML benchmarks which recognizes that the XML data that DBMSs manage are quite varied and no one database schema and workload can properly capture this variety. Thus, the members of this benchmark family have been defined for capturing diverse application domains.

In this report we briefly discuss the XBench XML benchmark and report on the relative performance of three commercial DBMSs: X-Hive, DB2 and SQL Server. We also describe the potential issues when storing XML documents into relational DBMSs.

Abstract: 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 efficiently 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 different 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 will 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.
