Box 1: star schema
In computing, the star schema is the simplest style of data mart schema and is the approach most widely used to
develop data warehouses and dimensional data marts. The star schema consists of one or more fact tables referencing
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 with 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.
