Quizplus · Accepted Answer

A tuple represents a specific instance of the entity represented by a relation, containing a set of attributes (columns) with corresponding values for that instance. A resource is a more general term that refers to any piece of data that can be identified and accessed over a network, while an agent refers to a user or system that interacts with a computer system. An event is a specific occurrence or happening that can be recorded and analyzed, but is not necessarily related to an entity in a database.
