The data binding process involves setting up the data connection and associating the data with the report or a dashboard item.
Setting up the data connection involves configuring the data source connection properties and then fetching the data by use of data models or data sets based on a data source. Next, while designing a report or a dashboard, all you need to do is to connect to these existing data models or data sets, or create a new one.
You need to have complete understanding of what all types of data sources are supported and how these are configured, and the complete knowledge of datamodels, direct query model, cached model, and datasets, and other related operations.
