What is a GUID?
GUID (aka UUID) is an acronym for 'Globally Unique Identifier' (or 'Universally
Unique Identifier'). It is a 128-bit integer number used to identify resources.
The term GUID is generally used by developers working with Microsoft technologies,
while UUID is used commonly used elsewhere.
How are GUIDs used?
GUIDs are used by enterprise software developers, progammers, engineers,
database administrators, and testers in systems and application development
and testing. They are used in Java, C#, Python, C++ , SQL databases, and
non-relational Cloud databases as primary keys, versions, component identifiers,
or just about anywhere else a truly unique identifier is required.
How unique is a GUID?
128-bits is big enough and the generation algorithm is unique enough that
if 1,000,000,000 GUIDs per second were generated for 1 year the probability
of a duplicate would be only 50%. Or if every human on Earth generated
600,000,000 GUIDs there would only be a 50% probability of a duplicate.
