摘要：
本文提出了一种新的评价数据仓库性能的基准。基准测试对系统用户比较不同系统的性能或系统工程师测试各种设计选择的效果都很有用。虽然TPC（事务处理性能委员会）标准基准解决了第一点，但它们的可调性不足以解决第二点。我们的数据仓库工程基准（DWEB）允许生成各种特定的合成数据仓库和工作负载。WEB是完全参数化的。但是，两个级别的参数化使其易于调整。由于DWEB主要满足工程基准测试需求，因此它是TPC标准基准测试的补充，而不是竞争对手。最后，DWEB被实现为一个Java自由软件，可以与大多数现有的关系数据库管理系统。
英文摘要：
We present in this paper a new benchmark for evaluating the performances of data warehouses. Benchmarking is useful either to system users for comparing the performances of different systems, or to system engineers for testing the effect of various design choices. While the TPC (Transaction Processing Performance Council) standard benchmarks address the first point, they are not tuneable enough to address the second one. Our Data Warehouse Engineering Benchmark (DWEB) allows to generate various ad-hoc synthetic data warehouses and workloads. DWEB is fully parameterized. However, two levels of parameterization keep it easy to tune. Since DWEB mainly meets engineering benchmarking needs, it is complimentary to the TPC standard benchmarks, and not a competitor. Finally, DWEB is implemented as a Java free software that can be interfaced with most existing relational database management systems.
