What are data pages in pega

A data page loads data to the clipboard for the system to use. The system can access data from the data page on demand. On the first reference of a data page (in data transform, activity, etc), the Data page will be created in the clipboard and loads the data to use.
Structure of the data page:
We can create a data page with two types either a single page (holds a single object/page) or List (Page List - holds multiple objects/results/pages) type.
The first important thing on the data page is Mode(after loading a data page if the data is readable, editable, or savable) 
We can create a data page in three modes.
  1. Read Only (Node, Requestor, and Thread)
  2. Editable     (Requestor and Thread)
  3. Savable      (Requestor and Thread)
