Hi, there is no high relation to kettle, but please advice me.
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 Kettle, but need general advice.
Thanks,
