Dimensional Modelling
Overview
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 attendees 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.
Delegates will learn how to
- Understand the pros and cons of relational and dimensional modelling.
- Design dimensional models from analytical business requirements.
- Produce effective star schemas that deliver the analytical capabilities that the business requires.
