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

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

Answer: B

Correct answer: second step.

The second step is where the structure is inferred: the functional dependencies among the columns, and from them the primary keys, and then the foreign keys that link the tables. The first step is only a survey of what has arrived, and the third checks whether the implied referential integrity constraints are actually satisfied.
