What is a Universally Unique Identifier (UUID)?
A Universally Unique Identifier (UUID), also known as a Globally Unique Identifier (GUID), is a unique identifier used in computer systems. Typically 128-bit integers, UUIDs are usually generated randomly. Each UUID is unique worldwide and is often used to identify, track, or associate unique IDs or items. You'll find them in databases, network protocols, file systems, and many other applications.
Uses of UUIDs
- Databases: Assign unique IDs, or primary keys, to records in database tables, preventing conflicts.
- File Systems: Uniquely identify files, especially in large systems, to avoid duplicate names.
- Merge Operations: Ensure accurate matching of data from different sources during merging or synchronization.
- Association: Establish relationships between tables in relational databases.
- Distributed Systems: Uniquely identify components in systems running across multiple computers or networks.
UUIDs are widely used across many different applications and systems as unique identifiers.
RFC 4122 and UUID Creation
The creation of UUIDs follows standards defined in RFC 4122. This standard outlines methods for creating unique identifiers to ensure they are universally unique. A random UUID creator can create these identifiers based on algorithms that produce statistically unique results, adhering to the specifications of RFC 4122.
Conclusion
Using a Universally Unique Identifier (UUID) is essential in various computing environments to ensure the uniqueness of records, files, and components. Whether you need a unique ID for a database entry or to ensure files in a large system don't overlap, UUIDs provide a reliable solution.
