Bus Schema Vs Str Schema Vs Snow Flake Schema

Bus, Star, Snow flake Schemas in Data Warehousing

BUS Schema is composed of a master suite of confirmed dimension and standardized definition if facts.

Star schema is a type of organizing the tables such that we can retrieve the result from the database quickly in the warehouse environment.

Snowflake Schema, each dimension has a primary dimension table, to which one or more additional dimensions can join. The primary dimension table is the only table that can join to the fact table.
