Functional dependence means that for each value of the table's primary key, there should be just one value for each of the attributes in the record, and that the primary key determines that value. The attribute should be functionally dependent on the value of the primary key. For example, if employee ID is a primary key, then for each value of employee ID, there is exactly one value for each of the attributes included in the record, and the employee ID determines that value.
