Overview
Dimensional Modellingis a practical training course for teams that need structured, instructor-led skills in Dimensional Modelling Introduction, Gathering, Measures. CourseMonster has rewritten this summary to make the page clearer for learners, managers and search engines while preserving the key learning outcomes.
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.
Target Audience
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 Developing A Modern Business Intelligence System should not attend this course.

Thinking about Onsite?
If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. Its a cost effective option. One on one training can be delivered too, at reasonable rates.
Submit an enquiry from any page on this site and let us know you are interested in the requirements box, or simply mention it when we contact you.
