About Variables

Hello kingsley J 

Variables are used to store values, which can be changed during execution of your code or process. You can define the type of variables and use them for storing the same type of value (Integers, text, Boolean etc.) , using these variables you can transform or change the data in your code or process. 

In Appian we have Local variables, Rule Inputs(Global Variables) and Process variables.

I would recommend you to go through the documentation for better understanding. 
1. Local Variables
2. Interface variables and Inputs

3.  Process Variables
