Guardians of the Star Schema

Are your visuals only reacting very slowly to changes of filters? Are you suffering from the “DAX-is-complicated” syndrome? Is the model view very crowdy? All of these symptoms are very common, if your data model is not in the shape of a star schema. In Power BI you should always first start with a star schema, before you start your adventure into more complicated challenges. Luckily, transforming any data model into a star schema is not as complicated as it might sound: Assign attributes to either a fact or dimension table, normalize the fact table, denormalize the dimension tables, add a date table, transform blanks and flags into meaningful descriptions, resolve hierarchies into dedicated columns – and you are on your best way to become a Guardian of the Star Schema.

Markus will also be a speaker on November 21. For more details please visit this site.
