    Business Intelligence-To be a MBA & DBA

    BI 的系统基础是数据仓库(Data Warehouse),建设数据仓库需要你即使一个MBA又是一个DBA. You should be hybrid MBA(business analyst)/DBA(database administrator).
     
     
    可见建设BI系统并不是一个单纯的技术工作。BI首先要强调的是对business 的认识、理解、分析和确认。而且可能是一个反复的过程。如果你想马上进入建模的阶段,或者听我讲Dimensional Modeling的要点的话,你可能要失望了,我要强调的是先做好一个MBA。
     
    粗浅而言,建设BI系统和其他商业系统没有什么太大不同之处,BI比较强调的过程主要由下组成:
    1. 业务需求的调研和确认
      ->2.结构设计和工具选择
      ->3.建立维度模型(Dimensional Modeling),物理模型设计(Physical Design),ETL 设计和开发
      ->4.BI Application开发
    5.开发
    6.数据增长
    7.维护
