A data page in a Pega Platform application retrieves data from a specified data source and caches it in memory. The integration to the data source is managed by a data page, which separates business activities from any integration details. This separation enables app developers to use supplied data in their apps without having to know the data source or connection specifics. Unlike most Pega Platform pages, applications seek to populate the contents of a data page only when the page is requested, rather than through an explicit action. Data pages are classified as declarative rules since their content is available on demand. To distinguish a data page from other pages in memory, Pega Platform automatically adds the characters D_ to the name.
A developer must give four crucial pieces of information when creating a data page. They are as follows :
* Structure of the page
* Object Type of the page’s content
* Edit Mode supported
* Scope of the data page
