During case processing, each page element will be available in memory in a structure called as Clipboard.

Clipboard:

A clipboard is the portion of the memory on the server reserved by pega for the data generated by the application.

if we have single elements then the data are directly available in the pyWorkPage but when we a page mode ( page/pagelist ) data, then those data are available under pyWorkPage. These pages are called as Embedded pages.

Parent and Child Data:

when we run the parent case , the parent case data will stored in the pyWorkPage when we run the child case, parent case will data will be moved to pyWorkCover and child case data is stored in pyWorkPage. once the case is completed, the parent class data is again stored in the pyWorkPage.

Pages in Clipboard:

There are 4 types of pages in pega: a. user pages b. Data Pages c. Linked Property pages d. System pages

UserPages:

It Contain pages created by the user action either directly or indirectly user pages contains the current case data related to the work being performed in selected thread. while user process a case , all the pages used to store data are listed in the user pages category. eg: in our online shopping case type, what ever data we enter in the user form is available in pyWorkPage under UserPage Category userPage-> pyWorkPage

DataPages:

It contains the data that are retrieved from the external system

eg: calculate the cost of certificatione exam based dollar price.

Linked Property Pages:

Contains read only pages created by Linked properties which contains information from data objects referenced by a linked property. They are advanced constructs basically used by SSA or LSA
