Dimensional Modeling

A modeling approach that organizes analytical data structures around facts and dimensions.

Dimensional modeling is one of the most widely used enterprise design approaches in data warehouse architecture. Measurements are stored in fact tables, while contextual information is stored in dimension tables. This makes reports, dashboards, and analytical queries more intuitive and performant. Dimensional modeling is not just a technical schema pattern; it is also a semantic decision about how the business chooses to quantify reality.
