Will return a GUID.
A GUID (Globally Unique Identifier) is almost guaranteed to be unique, even without a central authority to ensure uniqueness. They are used to identify different things across different systems with a minute chance of collision. This is not only related to databases, they can be used for creating unique file names.
Recalculation Trigger is the value that will recalculate the function each time it changes.
