A Dimensional Data Model is at the core of most Business Intelligence and Data Analysis systems. Unlike normalized, transactional database designs built for efficient writes and ease of application development, dimensional data models are build for efficient reads and ease of reporting and analytics. Designing dimensions around subject areas such as customers, products, locations, and employees as they change over time can be the most challenging part of a well-designed Dimensional Model.
After an overview of Dimensional Modeling, the presentation will cover the fundamentals of type 1, 2 and 3 Slowly Changing Dimensions (SCD), how and when to use them, and how to combine them.
