Question

Quizplus · Accepted Answer

To begin designing physical files and databases, it is necessary to have normalized relations, definitions of each attribute, and technology descriptions. Normalized relations help to ensure data consistency and reduce the likelihood of errors. Definitions of each attribute clarify what information will be stored in each field. Technology descriptions inform which technology will be used to create and manage the physical files and databases. Therefore, all three requirements (normalized relations, definitions of each attribute, and technology descriptions) are necessary to begin designing physical files and databases, making option D the correct answer.
