What is a page definition used for in Pega?

A page definition in Pega is primarily used to define the structure of the page property. It acts as a blueprint that outlines the characteristics of the page property, including its data types, purpose, and other essential attributes. This definition is crucial in Pega applications as it provides clarity on how data is organized and accessed within a particular context, ensuring the integrity and usability of the data in processes and user interfaces.

While creating temporary data storage, representing a view of the data in the user interface, and optimizing performance are all important aspects of working with data in Pega, they do not directly pertain to the core function of a page definition. Instead, they represent actions or functionalities that may involve or benefit from the structured approach provided by the page definition, but they are not the definition's primary role.
