Logical data structures, also called entity-relationship models, are models used to define a high-level model of data and the relationships contained within. In this course, you'll learn about the stages of data lake maturity. You'll explore temporal database tables and how to manage them. You'll also learn how to define slowly changing dimensions and how to implement them. You'll then move on to explore logical file and folder structures for data ingestion. You'll discover how PolyBase can be used to connect to external tables. Finally, you'll explore the best practices for accelerating queries. This course is one in a collection that prepares learners for the Data Engineering on Microsoft Azure (DP-203) exam.
