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

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

Answer: B

Correct answer: second step.

Determining functional dependencies, primary keys and foreign keys all belong to the second step, in which the structure implied by the data is worked out. The first step is simply to see what is there - the row count and the columns - and the third is to test whether the referential integrity constraints implied by the foreign keys actually hold.
