In the views task pane you can set any view you want as default with the right click menu.
The form will always start with the default view. Unless in Open Rules (Form Options) you set a rule action to switch to a different view.
When you create a DB form it makes the initial view for you.
However the concept of InfoPath is that you can have multiple views or ways to represent the data but the same data throughout the form.
Your data can be viewed and manipulated in any view.
Add a new view, Drag the fields you want on to it. Create a button on your main view or open rules to switch to the new view and you can move from one view to the other. Or send certain users to a certain view or hide a certain section, whatever you need.
