A real Snowflake is not just one fluffy white ice crystal, but a cluster of thousands of tiny ice crystals that form into a snow flake and fall collectively from a cloud. However, if we look around us we can see snowflakes can take many different shapes. Different types of snowflakes we can create can be animal, vegetable or mineral!

Snowflake Physical Data Model
The symmetrical design of a snowflake pattern can be very useful in creating database design. The Snowflake Physical Data Model is named such because it has many levels radiating outwards which resembles a snowflake. Snowflake Designs are used to support Data Warehouses or Data Marts. These designs are characterised by a central Table, which hold "facts," and have multi-level "dimension" tables radiating outwards.
