Quizplus · Accepted Answer

A data model is a logical representation of the structure of the data, depicting how data is connected and structured. Option A is incorrect because a data model is created before the database is designed to give a blueprint for how the database should be constructed. Option B is incorrect because a unique attribute is associated with only one entity instance, but that does not necessarily relate to the data model. Option D is incorrect because data models explicitly describe relationships between data.
