Data modelling in Power BI makes it possible to connect multiple data sources on the basis of which you can create clear and attractive reports.
Creating reliable multidimensional reports requires the usage of multiple data sources which cooperate with each other. Thanks to the great possibilities that Power BI data modelling gives it is not only possible but also easy and intuitive.
In Power BI data is connected through relationships. By making use of a relationship between the data sources, the tool allows you to create attractive and valuable visualizations. With the help of data modelling you can create individual, unconventional calculations in order to display particular data sets.
