This method involves organizing data into dimensions and facts, where dimensions are used to describe the data, and facts are used to quantify the data. For instance, suppose a business wants to ... This snowflake schema stores exactly the same data as the star schema. The fact table has the same dimensions as it does in the star schema example. The most important difference is that the dimension tables in the snowflake schema are normalized. Interestingly, the process of normalizing dimension tables is called snowflaking.

This database modeling method provides an efficient way to retrieve information and organize the data so that it can be looked at multiple ways, providing a means of increasing business performance and reaction time.
