Dimensional modelling is an integral part of any BI (Business Intelligence) system and can be used within the data warehouse and/or the data marts. This 3 day course assumes no prior knowledge of dimensional modelling. It starts by discussing what a data warehouse is, how they are designed and the part that dimensional modelling plays.
The vitally important process of requirement gathering is covered and delegates are shown how to:
- Collect the analytical requirements of the business users
- Create a logical model of these requirements
- Create a star schema from those requirements
The relational and dimensional models are compared and contrasted, with particular reference to the current Kimball/Inmon debate.
The course then looks in great detail at dimensional modelling itself and finally ends with a summary of possible BI architectures.
