在数据仓库项目中,数据探索阶段的主要目的是什么?


正确答案:
答:
在逻辑数据映射进行之前,需要首先对所有的源系统进行分析。对源系统的分析通常包括两个阶段,一个是数据探索阶段(Data Discovery Phase),另一个是异常数据检测阶段。
数据探索阶段包括以下内容:
1.收集所有的源系统的文档、数据字典等内容。
2.收集源系统的使用情况,如谁在用、每天多少人用、占多少存储空间等内容。
3.判断出数据的起始来源(System-of-Record)。
4.通过数据概况(Data Profiling)来对源系统的数据关系进行分析。
数据探索阶段的主要目的是理解源系统的情况,为后续的数据建模和逻辑数据映射打下坚实的基础。
