Data Elements in Pega

Pega PRPC handles data through different data elements. As part of our implementation, we create a data model to represent and store different information. The fundamental unit of data model in pega is called "Property". 

There are different property modes in pega for our convenience. For example if we want to store a single piece of information like Name then we use Single Value Property and for a collection of information like Address we use Page. Here is the list of property modes:-

Single Value:- Use to store a single Text , number or Date e.g. "Pega",1234.

Value List:- Use to store ordered list of values e.g. For job history of employee we can use value list to store Job(1)='App Dev', Job(2)='Pega Dev' etc.

Value Group:- Use to store unordered list(like key value pair). e.g. Phone(Home)='1234', Phone(Office)='2345' .

Page :- To store multiple embedded properties e.g. Address Page with properties HouseNo, PinCode, City etc.

PageList:- To store ordered list of pages  e.g. Address(1), Address(2). 

PageGroup:- To store unordered list of pages e.g. Address(Home), Address(Office).

There are also some advanced property type like Java Objects(String,Integer, Class Object) or List of Java Objects.
