Data Warehouse Schema Architecture

Data Warehouse environment usually transforms the relational data model into some special architectures. There are many schema models designed for data warehousing but the most commonly used are:

- Star schema

- Snowflake schema

- Fact constellation schema

The determination of which schema model should be used for a data warehouse should be based upon the analysis of project requirements, accessible tools and project team preferences.
