Real world data warehouse designs rarely resemble the simple star schemas found in product demos or introductory courses - a single fact table, fully additive facts, and several standard dimension tables.
This course takes you beyond fundamental principles of dimensional design, providing an extended set of techniques to address real-world complexity.
The course begins with a brief review of the core concepts dimensional modeling. These fundamentals are then built upon in four areas: multi-star designs, alternative fact table designs, dimensional intricacy, and scaling.
This comprehensive treatment provides the breadth and depth you will need to meet your data warehouse design challenges - whether you are building a dimensional data warehouse, a Corporate Information Factory, or stand-alone data marts.
You Will Learn
- Why most subject areas require multiple fact tables, and how to identify them
- When to use alternatives to the basic transaction fact table, including periodic snapshots, accumulating snapshots, and type-specific stars
- How to cope with dimensional intricacy, using techniques such as bridge tables, mini-dimensions, time-stamped dimensions and hybrid slow changes
- Techniques to ensure your data warehouse will scale as new subject areas are added Geared To
This course is geared toward professionals who need a comprehensive understanding of star schema design.
