A snowflake schema is a way of arranging data in a database. It gets its name from the way it looks, with different pieces of data stored in different places like snowflakes stored in many different places. In a snowflake schema, all of the data is organized into tables, similar to a jigsaw puzzle. These tables can all be linked together, making it easier to find, store and retrieve data. For example, in a snowflake schema for a store, each product would have its own table, which would be linked to a customer table and an address table. That way, when someone wants to look up a customer, they can look up all of their information at once, instead of having to piece it all together from different places.
