基于ODS的数据仓库研究与实现

Research and Implementation of Data Warehouse Based on ODS

数据仓库 (DW)在决策支持系统起着举足轻重的作用 ,在数据的存储和挖掘中有着诸多优势 ,但对处理实时数据的处理效率不高 ,操作数据存储 (OperationalDataStore)的出现弥补了数据仓库在效率上的不足。对ODS作了系统论述 ,并提出了相应的解决方案。

Data Warehouse is the core of DSS, which has many advantages in data storage and data mining, but DW is hard to deal with real-time data. Operational Data Store can recover this shortcoming. This paper discusses the whole ODS system, and bring out an effective solution.
