Level: Beginner to Intermediate
Prerequisite: This course assumes basic understanding of data warehousing fundamentals.
Analytics Consultant and Educator
This data modeling techniques course explores different situations facing data modeling practitioners and provides information and techniques to help them develop the appropriate data models.
BI and analytics systems challenge the proven data modeling techniques of the past. The expanding scope of data management technologies, consumption demands, and data science processes require updated modeling skills. The data modeler’s toolbox must address relational data, NoSQL data, dimensional data, and master data. Modeling processes must include both top-down requirements-driven and bottom-up discovery methods. For those with data modeling experience, this course extends their skills to meet today’s modeling challenges. Those new to data modeling are introduced to the broad range of modeling skills needed for BI and data warehousing systems. Those who need to understand data models, but not necessarily to develop them, will learn about the various forms of models and what they are intended to communicate.
