Advanced Dimensional Modeling: Techniques for Practitioners
Duration: Two Day Course
Prerequisite: This course assumes a basic understanding of dimensional modeling concepts, techniques, and terminology.
Offered by Chris Adamson through TDWI Onsite Education
The companion course to the book Star Schema: The Complete Reference.
Comprehensive coverage of dimensional modeling principles, processes, and deliverables, from the author of Star Schema: The Complete Reference. Students learn the complete set of best practices—from multiple fact table designs to bridge tables to advanced slow change processing. Students learn to match these techniques to real-world business complexity and explore their impacts on BI and data integration tools. Students also learn how to fit dimensional modeling into agile development frameworks, and they receive templates for capturing requirements and designs.
