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.

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)
