The identifier of an entity will become the ________ of the new table.

  • A.foreign key
  • B.main attribute
  • C.
    primary key
  • D.identity key

Answer: C

Correct answer: primary key

The transformation is direct: each entity becomes a table, each attribute becomes a column, and the entity’s identifier becomes the table’s primary key. That correspondence is what makes the relational design follow mechanically from a well-made data model, with the relationships then represented by foreign keys.
