TRUE. An identifier is a candidate key that has been selected as the unique, identifying characteristic for an entity type. In database design, an entity type represents a type of object or concept that has a set of attributes or properties. For example, an entity type could be "customer" or "product" in an e-commerce system.
Each instance or occurrence of the entity type is uniquely identified by an identifier, which is a set of one or more attributes that together uniquely identify the instance. A candidate key is a set of one or more attributes that could potentially serve as an identifier for an entity type. However, not all candidate keys are suitable as identifiers, as they may not be unique or stable enough to reliably identify the instances of the entity type.
Therefore, a single candidate key is selected as the identifier for the entity type, and this key is used as a reference or foreign key in other tables that have a relationship with the entity type. In summary, an identifier is a specific candidate key that has been chosen as the unique, identifying characteristic for an entity type. It is an essential element of database design that enables data to be organized and accessed efficiently.
