What is dimensional analysis and how do we use it?

Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value. It is a useful technique.

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?

Examples of fact data include sales price, sale quantity, and time, distance, speed and weight measurements.
