Conceptual design

  • A.Is a documentation technique.
  • B.Needs data volume and processing frequencies to determine the size of the database.
  • C.Involves modelling independent of the DBMS
  • D.Is designing the relational model.

Answer: C

Correct answer: Involves modelling independent of the DBMS

Conceptual design captures what the organisation needs to record - entities, attributes and relationships - without reference to any particular product. Choosing tables and types is logical design, and sizing and tuning belong to physical design; keeping them separate is what lets the same conceptual model be implemented on any DBMS.
