ODS与EDW的区别
维基百科对于ODS的定义为”An operational data store (or “ODS”) is a database designed to integrate data from multiple sources for additional operations on the data. Unlike a master data store, the data is not passed back to operational systems. It may be passed for further operations and to the data warehouse for reporting.” 翻译过来”ODS是一种数据架构或数据库设计的概念,出现原因是来自于当需要集成来自多个系统的数据,结果又要给一或多个系统使用时。”
