In most Apps you will need some variables that are not part of the data saved in the database. For example, if you want a search box in a User Interface, the search text needs to be saved somewhere (and used for filtering the data to be displayed).
Variables are called Runtime Properties in Appfarm.
Runtime Properties may be added to a built-in Data Source called App Variables (for holding single variables to be used in your App), or they may be added to Data Sources.
A Runtime Property may be of type Value or Function.
Value is used whenever you want to set that value yourself (e.g. from a User Interface, or from an Update Object Action Node)
Function is a calculated property. E.g. you may have a Runtime Property Full name with a function return firstName + " " + lastName
