# Build Business Views

Business views provide report users with a business-oriented view, and calculations on a data source. They shield report end users from having to understand physical structure, and enables the easy building of reports.

To make use of business views in Page Report Studio and Web Report Studio, you need to first define them at report design time in JReport Designer.

To add a business view to a catalog:

1. In JReport Designer, click File > Catalog Management > Open Catalog to open the catalog to which you want to add the business view.

2. In the Data tab of the Catalog Browser, expand the desired data source, right-click the Business View node and then click Add Business View.

3. In the Input Business View Name dialog, enter a name for the business view, and then click OK.
4. In the Add Table/View/Query dialog, select a resource you want from the left box and click to add them into the right box. Click OK.

5. In the Business View Editor window, add elements to the business view.

6. Define hierarchies on the business view to allow end users to drill report data to particular groups.
7. Create some predefined filters for the business view to narrow down records if required.
8. Configure security for the business view if necessary.
9. Click File > Save to save the business view.
10. Click File > Close to close the window. The business view will now have been added to the catalog.
