摘要: 提出了一个ETL(Extraction-Transformation-Loading)优化框架并对ETL过程的逻辑优化进行了研究,把优化问题建模成状态空间搜索问题。每个ETL工作流看作一种状态,通过一系列正确的状态变换来构造状态空间,并且提出算法来获得最小执行时间的ETL工作流。理论分析和实践表明其具有良好效果。
关键词: ETL 工作流 优化
Abstract: An optimization framework is provided in the paper , and the logical optimization of ETL processes is researched. The optimization problem is modeled as a state-space search problem. Each ETL workflow is considered as a state and the state space is fabric
Key words: ETL, Workflow, Optimization
