A data structure that holds name-value pairs. Pages are stored in the system memory or in the database. Various types of pages are defined in the system, such as data pages that are created when the data is referenced, named and unnamed pages, parameter pages, clipboard pages, and so on.
Every unit of information in an application is a pairing of a name and a value, known as a data element. For example, a data element that stores the email address of a customer has the name "email," and the value "firstname.lastname@example.org." Pages store data elements so that the application can use it to process the case.
