摘要: Data warehouse (DW) design is based on a set of requirements expressed as service level agreements (SLAs) and business objects (BLOs). Populating DW system from information sources realized with extract-transform-load (ETL) processes SLAs BLOs. The entire task complex, time consuming, hard to be performed manually. This paper presents our approach the requirement-driven creation ETL designs. Each requirement considered separately respective produced. We propose an incremental method for consolidating these individual designs creating that satisfies all given requirements. Finally, produced sent engine execution. illustrate through example TPC-H report experimental findings show effectiveness quality approach.
