Conformed Dimensions

This dimension is consistent and the same across multiple fact tables in a data warehouse. The dimension tables are designed once and used across various areas, maintaining consistency.

List of countries/states where the company is doing business.

An excellent example of a conformed dimension is a "Date" or "Time" dimension. Imagine a data warehouse for a retail business that has two fact tables: "Sales" and "Inventory". These fact tables might have a "Date" dimension that tracks when a sale or inventory count was made.

In this example, Date, Product, and Store dimensions remain constant across multiple fact tables.
