Question

____ are entities that have an identifiable field or group of fields that represent the key.

Answer 1

Entities in a database have a primary key field that uniquely identifies each record; for instance, a Student ID in a Student table.

Step-by-step explanation:

Entities that have an identifiable field or group of fields that represent the key are often referred to as database entities. In a relational database, these entities are typically represented by tables, where the key field, known as a primary key, uniquely identifies each record within the table. For example, in a student database, the entity could be a Student table with a primary key field being the Student ID, which ensures that each student is uniquely identified.
