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.

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.
