any
number of dimension tables. The star schema is an important special case of the snowflake schema, and is more
effective for handling simpler queries.
Example:

Incorrect Answers:
The data in the question is not normalized.
The snowflake schema is a variation of the star schema, featuring normalization of dimension tables. Example:

Note: A snowflake schema is a logical arrangement of tables in a multidimensional database such that the entity
relationship diagram resembles a snowflake shape. The snowflake schema is represented by centralized fact tables
which are connected to multiple dimensions.[citation needed]. “Snowflaking” is a method of normalizing the dimension tables in a star schema. When it is completely normalized along all the dimension tables, the resultant structure resembles a snowflake with the fact table in the middle.
Box 2: dimension
The star schema consists of one or more fact tables referencing any number of dimension tables.
