What Is A GUID

A GUID (Global Unique Identifier), also known as a UUID (Universally Unique Identifier) is a 128-bit value often used for unique identifiers within databases or other scenarios where a unique identifier is required.

GUID collisions occur when two different entities share the same GUID as it's identifier. The set of all possible GUIDs is so vast that in order to have a 50% likelihood of a GUID collision, one would have to randomly generate approximately 2,710,000,000,000,000,000 GUIDs. This property makes GUIDs a good choice for uniquely identifying your data.
