Is the only difference between kimball and inmon, the Enterprise layer(EDW). I was googling around and found out that inmon also creates data marts using EDW. so does that mean, both these data marts are similar in structure for a given business process and source systems ?
Once the data marts are readily available for both the procedures, do they give same performance ?
correct me if i am wrong, the data warehouse is created first and then dimensional model is created on top of it for specific business requirements.(ER model to Dimensional model)
I was not able find information on how data marts are created in inmon model.I hope some of you could help me in this.
回答1:
Kimball = create all data marts and after with these we create a DW = Agile methodology = used if I don't have all informations at the beginning
Inmon = Create a DW and after we can create data marts = V Model = Used if I have global informations in the beginning
