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.
This course is aimed at people who work in the BI area. It is suitable for business analysts who need to understand the analytical requirements and turn those requirements into a model. It is also suitable for the IT professional who will turn those models into working OLAP (On-Line Analytical Processing) structures. Please note, delegates who have previously attended QADMBIS - Developing A Modern Business Intelligence System should not attend this course.
