Which level of Abstraction describes what data are stored in the Database ?
Answer: D
The three levels of abstraction in a database are the physical level, which describes how the data are stored, the logical level, which describes what data are stored and the relationships among them, and the view level, which describes the part of the database one user group sees. The question asks which level describes what data are stored, so it is the logical level, option (D). The physical level describes how, not what, and 'abstraction level' is not one of the levels.
