Description: The numeric identity refers to a unique numeric identifier assigned to a record within a database. This identifier is crucial for the organization and management of data, as it allows for the unequivocal distinction of one record from another. The numeric identity can be an integer, an alphanumeric code, or any other form of representation that ensures its uniqueness. Its main characteristic is that it does not repeat within the same data set, which facilitates the search, update, and deletion of records. Additionally, the numeric identity is fundamental for establishing relationships between different tables in relational databases, where primary and foreign keys are used to link information. In an increasingly digitized world, the numeric identity has become essential in various applications, from database management systems to online services, where each entity, such as product, user, or transaction, needs to be uniquely identified to ensure the integrity and efficiency of the system.
