UUID (Universally Unique Identifier) is a 128-bit identifier standardized by RFC 4122. UUIDs are designed to be unique across time and space without requiring a central coordinating authority.
UUID v4 uses random or pseudo-random numbers and is the most commonly used version. UUID v1 is time-based and includes a timestamp, making it less suitable for privacy-sensitive applications.
UUIDs are widely used in software development for generating unique identifiers in distributed systems, databases, APIs, and any scenario where you need globally unique identifiers without coordination.
- • Database Primary Keys: Generate unique IDs for database records
- • API Development: Create unique identifiers for API resources
- • Session Management: Generate unique session IDs
- • Distributed Systems: Create unique identifiers across multiple servers
- • File Naming: Generate unique filenames to avoid conflicts
