The Power BI workspace is a container for datasets, reports, and dashboards.
Power BI can be divided into three categories for how you interact with data and create reports.
1) Report view: A canvas for building and viewing reports based on the datasets defined in Data view.
2) Data view: It helps you to inspect, explore, and understand data in your Power BI Desktop model. With Data View, you’re looking at your data after it has been loaded into the model.
3) Relationships view: Identified relationships between the datasets defined in Data view. When possible, Power BI Desktop identifies the relationships automatically, but you can also define them manually.
