A unique identifier (UID) is a value used to distinguish one entity from another within a given context. It ensures that each entity, whether it be a record, object, user, session, transaction, or any other type of item, can be uniquely identified without ambiguity. Unique identifiers are critical in various systems and applications to prevent duplication, enable accurate referencing, and ensure data integrity.
IDs with issuing authorities are identifiers that are generated, managed, and validated by a central or authoritative entity. These authorities ensure the uniqueness, integrity, and sometimes the security of the IDs. Here are some common types of IDs with issuing authorities:
IDs that do not require a central issuing authority are designed to be self-generated and ensure uniqueness in a decentralized manner. These types of IDs are especially valuable in distributed systems where coordination between different parts of the system is difficult or impractical. Here are several examples of such IDs:
Best practices for creating, managing, and using IDs (Identifiers) are crucial for ensuring uniqueness, security, interoperability, and scalability. Here are some key best practices to follow:
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. It is standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE) and specified in RFC 4122. The primary purpose of a UUID is to provide a unique identifier that can be used across different systems without requiring a central coordinating authority.
UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify objects or entities on the internet. UUIDs have different versions, each with specific methods of generation and intended use cases.

CUID stands for "Collision-resistant Unique Identifier." It is designed to be a more robust alternative to other unique identifier systems like UUIDs (Universally Unique Identifiers). CUIDs aim to provide better performance, easier readability, and reduced likelihood of collisions (two identical identifiers being generated).
CUID (Collision-resistant Unique Identifier) is a unique identifier system designed to be more robust and user-friendly compared to traditional UUIDs. There are different versions of CUID, each with its own use cases and features. The primary versions of CUID are CUID (original version) and CUID2.
