Fact table allows the measurement and the values of the facts of the data to be contained inside the table. This table consists of the foreign keys and primary keys of the dimension tables. It is located in between the star schema or snowflake schema. It provides values that are additive and independent variables through which the dimensional attributes are analyzed. This table consists of the grains, which consist of atomic level of data and through which the facts in the tables are defined. Each record defines the independent facts that provide higher level of data to be given to the user. It is useful in representing the data due to easy storage and less memory to be taken to the facts of the data that are associated with it.
