Slowly changing dimensions data modeling course, in this course we delve into the intricacies of Slowly Changing Dimensions (SCD) data modeling. SCD addresses the challenge of managing data that evolves over time, ensuring accuracy and historical preservation. We explore three main types of SCD: Type 1, where old data is replaced with new values; Type 2, retaining historical versions by adding new records; and Type 3, storing both old and new data with additional indicators. Through practical examples and theoretical insights, you'll gain a comprehensive understanding of SCD strategies, enabling you to effectively organize and analyze evolving datasets. Join us to master the art of Slowly Changing Dimensions data modeling.
