# Conformed vs Role Playing

Conformed and role-playing dimensions are both concepts in data warehousing, but they serve different purposes.

A conformed dimension is a dimension that is shared across multiple fact tables in a data warehouse. A conformed dimension has the same meaning and structure in all fact tables and is used to maintain consistency and integrity in the data warehouse.&#x20;

For example, a **Date dimension** could be used in multiple fact tables that **record sales**, **inventory**, and **customer data**. The Date dimension maintains its structure and meaning across all fact tables, ensuring consistent and accurate analysis.
