When assessing the table structure of an acquired set of tables with data, determining primary keys is (part of) the:

  • A.first step.
  • B.second step.
  • C.third step.
  • D.fourth step.

Answer: B

Correct answer: second step.

Determining the primary keys belongs to the second step, along with the functional dependencies from which they follow and the foreign keys that depend on them. The row and column survey comes first, and testing whether the referential integrity constraints implied by those foreign keys actually hold comes third.
