On the other hand, if no candidate key
arises, then one needs to dig deeper for a better understanding of what is happening.
But if all candidate keys
are taken into account (that is considered here), although there are no partial dependencies on A, we have a partial dependency B [right arrow] D on candidate key
BC, implying that the relation is not in 2NF.

Key phrase extraction from a body of text relies on an evaluation of the importance of each candidate key
Such an attribute, or combination of attributes, is called a candidate key
The two foreign keys combine to form a candidate key
ISAKMP is the leading candidate key
management standard in the Internet Engineering Task Force (IETF).
Each candidate key
consists of the attribute or attributes used to label a distinct row in a table.
Any form field matching a common candidate key
suffix such as NAME, NO, NUMBER, or # may represent an entity (e.
A candidate key
is a set of attributes that uniquely identify each row.
