The Types of Dimensions in a Star Schema, and How to Use Them

# Understanding Star Schemas: A Guide to Organizing Business Data When companies organize their data for reporting and analysis, they use a structure called a "star schema" that groups information into two main categories: facts (the actual numbers and events) and dimensions (the descriptive details that help explain those numbers).
