Question

Quizplus · Accepted Answer

An entity relationship diagram (ERD) depicts the logical view of a database, showing the relationships between entities, attributes, and keys. It is a graphical representation of the data model that provides a clear and concise overview of the database's structure and organization. Therefore, option A is the correct choice. Option B (physical view of a database) is incorrect because an ERD does not show physical implementation details like data storage or indexing mechanisms. Option C (relationship between the user interface and the DBMS) and D (implementation of a client-server system) are also incorrect as they are not related to the purpose or scope of an ERD.
