Unique identification
The unique identifier, also known as the UUID (Universally Unique Identifier), is an internationally standardized 128-bit unique identifier. It is used to uniquely identify information in computer systems, ensuring that there are no duplicate identifiers.
UUIDs are generated randomly, which makes it extremely unlikely that collisions will occur, i.e. the same identifier being repeated for different objects. This makes them ideal for use in distributed databases and distributed systems in general.
In addition, UUIDs can be generated deterministically from specific information, ensuring that the same identifier is generated whenever the same information is used as a basis.
Because they are made up of 32 hexadecimal characters, UUIDs are easily represented in string format, which makes them easier to use in systems that require unique identifiers.
In short, unique identification is essential to guarantee the integrity and uniqueness of data in technology systems, avoiding conflicts and guaranteeing the correct identification of information.
