## What is UUID?

A UUID is like a secret code, unique and exclusive, that can be used to unlock the doors of information and resources in the digital world. Imagine each piece of data or file in a computer system as a treasure chest, and a UUID as the key to open it.

UUID is a string of numbers and letters that acts like a fingerprint, no two are alike, and it's a way to ensure that you are accessing the right chest, the one you intended to access. It's like a digital DNA, unique and unchangeable, that can be used to identify, trace and manage resources in a consistent and reliable way across space and time. UUID is a powerful tool that helps keep the digital world organized and secure.

## What is UUID version 4?

UUID version 4 is like the wild card in a deck of cards, it's unique and random. It's a way to generate a UUID that doesn't rely on any particular context, such as a timestamp or network information. Instead, it uses a random or pseudo-random number as the source of the generated UUID.

This makes it the most flexible version of UUID, that can be used in any type of application or system, it's like a lucky charm that can be used in any situation. Imagine you need to identify a resource but you don't know what kind of information you have, a UUID version 4 is like a universal key that can open any door, it's a one-size-fits-all solution. It's the most common version of UUID in the industry and many programming languages have libraries that can generate version 4 UUIDs.

## When is UUID version 4 useful?

UUID version 4 is useful in a variety of situations where a unique identifier is needed. Some common use cases include:

  • Identifying resources in a database: UUIDs can be used as the primary key for database records, ensuring that each record has a unique identifier that can be used to retrieve it.
  • Identifying files or other resources on a filesystem: UUIDs can be used as a unique identifier for files or other resources stored on a filesystem, allowing them to be easily located and accessed.
  • Identifying resources in a distributed system: UUIDs can be used to identify resources in a distributed system, such as a microservice architecture, ensuring that each resource can be uniquely identified and accessed.
  • Identifying resources in a web application: UUIDs can be used as unique identifiers for resources in a web application, such as sessions or user accounts.
  • Identifying resources in other application: UUIDs can be used in many other application like mobile apps, gaming, IoT, etc. where unique identification of any resource is required.

    • In general, any time you need a unique identifier that doesn't depend on any particular context, a version 4 UUID is a good choice.
