This accelerated class will go beyond the fundamental questions and tackle some of the most commonly asked questions and addresses the most common mistakes that people make. This course is based on real world experience in dealing with large data volumes and very complex models. The goal of this course is to equip you with the tool and knowledge to address your complex modeling challenges and to meet your demanding business needs.

All attendees should have basic knowledge about dimensional modeling AND some hands-on experience with dimensional modeling.

All data modelers and database administrators who have been developing or supporting data warehouses should attend this course. This course is intended to expand their knowledge of modeling techniques beyond the basic concepts. This course is also appropriate for other team members including project manager, staging system developers and end user application designers, including BI developers and data scientists.
