Managing properties and views
A view is a customizable layer between the reports and the raw tracking data you collect for a property. You use views to create specific perspectives of your data so that you see only the information you want in your reports. You can create multiple views for a single property. You might, for example, have one view to filter out all internal traffic, and another to include only activity in a specific directory or subdomain.
You have the option to restrict user access to specific views and thereby control who sees what data.
Analytics automatically creates one unfiltered view for every property you add to your account. With this original view, you have access to all data from the time you add the property. In order to always have at least one source of all property data, do not delete or add filters to this original view. When you delete a view, that particular historical perspective of the data is gone. When you add filters to a view, the data you exclude is unavailable. To preserve all your original data and also control the specific perspectives of that data, create a copy of your original view or set up additional views and customize each one to meet your reporting goals.
