Star Schema is centally Located by Fact Table surrounded by
Dimension Tables, hence it resembles Star so we call it
as "Star Schema"
Here We use the De-Normalized tables, If we use Normalizewd
tables that prefer the Snow-Flake Schema.
In Star Schema we have the less no. of tables, so we have
the duplicate records with non key attributes.
