Once you have built your query by adding the required objects to the Query panel, and defined query properties, you are ready to run the query. When you run a query, the universe asks the database to find the data that corresponds to the demands of each of the objects in the query.
Double-click a class node
(indicated by the folder icon) in the universe in the Universe pane. The
class expands to show objects.
Drag an object from the Universe Objects pane and drop it onto the Result or Select an object on the Universe Objects pane, then click the >> button.
Repeat step 2 for each object that you want to include in the query.
