Galaxy scheme

The Galaxy schema , like the star schema or the snowflake schema, is a data model that is used in OLAP systems.

In contrast to the star or snowflake schema, there are several fact tables that are linked to the same dimension tables. As a result, more complex company situations and the resulting key figures can be implemented.
