Sheets are the key components of a Qlik Sense application. They contain all the objects that carry information and provide a framework for analysis. There are three types of sheet that can be defined in a Qlik Sense application. These are private, approved, and community sheets:

• Approved sheets are all sheets that are defined by the author of the application. These cannot be changed by the user and are defined as read-only.
• Private sheets can be viewed only by the author of the application. These are not yet published for access by the end user.

• Community sheets are also private sheets but are defined and published by a user other than the author, who has been granted access to the application on the hub.
