I need an advice for creating my DW. I have some experience in creating DW (using Pentaho as BI server), I made an array of scheduled database queries which creates 4 dimension tables and 1 fact table (for sales reports). Now, there is a need for spreading out DW (for import, warehouse, logistic reports), so my question is:
Do I have to make more fact tables for each department (and dimension tables for those), or there is some other structuring model?
Of course, this time it will be done using ETL tool, but need general advice.

Thanks, Stevan

事实表代表您要分析的过程或事件。

如果没有要分析的新流程或事件，则不需要新的事实表。

也许您可以向我们提供有关您正在分析的内容的更多详细信息...
