In this one-day session you will learn how to develop Power BI Desktop data models. The session will describe data modeling fundamentals together with a development methodology covering how to create model tables with Power Query, how to create and configure appropriate model relationships, how to improve and enrich the data model design with usability features and calculations, and how to enforce row-level security (RLS) by defining and testing roles. This session introduces foundational theory and builds upon it by describing best practices and tips. Also, a strong foundation in Data Analysis Expressions (DAX) will be presented. This session will appeal to those new to Power BI Desktop data modeling, and also for those already developing data models (this session will be ideal for filing in any gaps in your knowledge).
