Answer / parthasarathi swain
A Dimension table is a table that contains detailed and
consistent data ie those data that are not frequently
changing in the other words we can say those as master data.
We use the primary key of the dimensional table as the
foreign key in the fact table. For one fact table we can
have more than one dimensional table.

Answer / shyam shah
A dimension table is a table in a star or snowflake schema
that stores attributes that describe aspects of a dimension.
For example, a time table stores the various aspects of time
such as year, quarter, month, and day. A foreign key of a
fact table references the primary key in a dimension table
in a many-to-one relationship.
