The data types what we create in the application can source data. It can source data from:

  1. No System of Record
  2. Pega System of Record (Local Storage )
  3. External System of Record (External Database)

Data Page cache the data on demand and store them into the clipboard for the further reference.

Definition of the data page:

SSSORM

Structure Scope Source Object Type Refresh Strategy Mode

1)Structure of the Data Page : 2 types : Page or List for single instance data page : Structure is Page -> retrieve only a single record for list instance data page : Structure is List -> retrieve multiple records.

2)Source : how does we get data from the database? for single instance data page : Source : Lookup -> means check for the parameter for list instance data page: Source : Report Definition

Different sources of data pages are: Look up ,Connector, Data Transform, Report Definition, Activity, Robotic automation, Robotic process automation and Aggregated sources.

Look up - used for single data page which will accept parameter. depending on the parameter records will be displayed Report Definition - mainly used for list data pages to connect with the data base to retrieve the records. Connector - used for external database connect. Data Transform- used to populate datapages with records. Activity - used to perform background processing and perform operations on the data page.

3)Scope: Node , Thread and Requestor.

Node:

EG: Sourcing the SuperMarket Items to a dropdown since it is same for all users.

if the data page to be accessible to all the users of the application , it has to be in node scope. Once the data is loaded it will not refresh again.
