 Hey guys, welcome to SSUnitech Susundi side and this is continuation of Power BI tutorial. We have made a great progress where we have learned about the query editor. It is time to start with the data modeling. What is the data modeling we will see in this video and what are the difference between query editor and data model. Basically, what is the data model? So in the data modeling, we will create the relationship between the tables as we are having multiple tables. So we will create the relationship between those tables. Next we will create the calculated columns over here. So let's assume we have two columns. First is quantity and second is the unit price. If we want to calculate the value then we need to multiply the quantity and unit price. So we will multiply and create the new calculated column. After that we will also create the measures inside the data modeling. So these are the main features in the data model and we will see one by one in the upcoming videos. So next is what is the difference between data model and query editor. So I want to explain in query editor we are connecting with the source files after that we are cleaning the data then shaping that data in a useful format. So here basically the structure of the data and prepare the data. In the data model we will create the relationship, we will create the calculated column and we will add the measures for analyzing the data. So in the query editor we will create the structure and prepare the data and inside the data model we will analyze the data. So this is the data model and the query editor. So these two are not equal. So in the next videos we will start with the relationships. So thank you so much for watching this video.
