## What are the advantages of dimensional modeling?

The predictable framework of a dimensional model allows the database to make strong assumptions about the data which may have a positive impact on performance. Each dimension is an equivalent entry point into the fact table, and this symmetrical structure allows effective handling of complex queries.

## What is the correct order of Modelling a warehouse?

The steps for physical data model design which are as follows: Convert entities to tables. Convert relationships to foreign keys. Convert attributes to columns.

## What is the level of normalization present in snowflake schema?

When it is completely normalized along all the dimension tables, the resultant structure resembles a snowflake with the fact table in the middle. The principle behind snowflaking is normalization of the dimension tables by removing low cardinality attributes and forming separate tables.

## How do you turn a star schema into a snowflake?

Merging Fournisseur to Assortiment should turn your snowflake into a star schema. But note that only because it is a star schema doesn’t make it more performant than the snowflake.

## What is star schema example?
