Fact Table
The centralized table in a star schema is called as FACT
table. A fact table typically has two types of columns:
those that contain facts and those that are foreign keys to
dimension tables. The primary key of a fact table is
usually a composite key that is made up of all of its
foreign keys.
In the real world, it is possible to have a fact table that
contains no measures or facts. These tables are called as
Factless Fact tables.
