What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. UUIDs are crucial in various applications, including database keys, transaction IDs, and unique identifiers for devices and users. Their uniqueness is paramount in ensuring that different entities are correctly and uniquely identified without conflicts.

Why Do You Need a UUID?

UUIDs are used extensively in software development and data management for several reasons:

  1. Uniqueness: As the name suggests, UUIDs are designed to be universally unique, minimizing the chances of duplication.
  2. Scalability: UUIDs support distributed systems and databases by ensuring unique identifiers without needing a central authority.
  3. Security: UUIDs can be used in cryptographic applications and secure transactions to ensure unique and unpredictable identifiers.
  4. Compatibility: Many modern databases and frameworks support UUIDs natively, making them a versatile choice for developers.
