Data Warehouse Engineering Benchmark

DWEB (Data Warehouse Engineering Benchmark) is a 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 standard decision support benchmarks address the first point, they are not tunable enough to address the second one and fail to model different database schemas. By contrast, 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 easy to tune.
