DWEB：一个数据仓库工程基准
DWEB: A Data Warehouse Engineering Benchmark
摘要：
数据仓库体系结构的选择和优化技术对决策支持查询性能至关重要。为了方便这些选择，必须评估所设计的数据仓库的性能。这通常是在基准测试的帮助下完成的，它可以帮助系统用户比较不同系统的性能，或者帮助系统工程师测试各种设计选择的效果。虽然TPC标准决策支持基准解决了第一点，但它们不足以解决第二点，并且无法对不同的数据仓库模式进行建模。相比之下，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。DWEB是完全参数化的，以满足数据仓库的设计需要。但是，两个级别的参数化使其相对易于调整。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。本文还提供了一个使用DWEB的示例。
英文摘要：
Data warehouse architectural choices and optimization techniques are critical to decision support query performance. To facilitate these choices, the performance of the designed data warehouse must be assessed. This is usually done with the help of benchmarks, which can either help system users comparing the performances of different systems, or help system engineers testing the effect of various design choices. While the TPC standard decision support benchmarks address the first point, they are not tuneable enough to address the second one and fail to model different data warehouse schemas. By contrast, our Data Warehouse Engineering Benchmark (DWEB) allows to generate various ad-hoc synthetic data warehouses and workloads. DWEB is fully parameterized to fulfill data warehouse design needs. However, two levels of parameterization keep it relatively easy to tune. Finally, DWEB is implemented as a Java free software that can be interfaced with most existing relational database management systems. A sample usage of DWEB is also provided in this paper.
