Identifitseerijad, commonly referred to as identifiers, are unique labels used to distinguish one entity from another within a specific system or context. These entities can be diverse, ranging from physical objects and individuals to digital resources and abstract concepts. The primary purpose of an identifier is to ensure that each entity can be unambiguously referenced and managed. Without effective identifiers, it would be challenging to locate, access, or manipulate specific items within a collection or database. Examples of identifiers are abundant in everyday life and in technical fields. A social security number uniquely identifies a person, a product's barcode distinguishes it from other items in a store, and a license plate number identifies a specific vehicle. In computing, universally unique identifiers (UUIDs) are used to label objects in a way that is virtually guaranteed to be unique across all systems. Similarly, database primary keys serve as identifiers for individual records. The design and implementation of identifiers are crucial for data integrity, efficient retrieval, and the overall functionality of many systems. The choice of an identifier often depends on factors such as the required scope of uniqueness, the expected lifespan of the entity, and the ease of use for both humans and machines.
