A database is called "self-describing" because it contains a description of itself.

  • A.
    True
  • B.False
  • C.None of the Above.
  • D.All of the Above.

Answer: A

Correct answer: True

A database stores the definitions of its own structure - tables, columns, data types, keys, indexes - as metadata in system tables, right alongside the user data. That is what “self-describing” means, and it is why a tool can inspect an unfamiliar database without any external documentation.
