Star Schema is a multidimensional model where each of its disjoint dimension is represented in single table.

Snow flake schema is similler to a star schema.
Snow flake schema is normalized multidimension schema where each of disjoint dimention is represented in multiple tables.
Star Schema can become a snow flake schema.

Check this out. A snowflake star schema is the same thing, but contains dimension rollups making it look like a snowflake in an ER Diagram.
