Изучите структуру UUID, типы и стандарты
UUID (Universally Unique Identifier) is a 128-bit identifier used to uniquely identify information in computer systems. UUIDs are standardized by RFC 4122 and are designed to be unique across space and time without requiring a central registration authority. They are commonly used in distributed systems, databases, and software applications.
