What is a transitive key?
Transitive Dependencies. Note: Transitive dependencies take their name from the transitive property in mathematics, which states that if a > b and b > c, then a > c. There are two determinants in the original items relation, each of which should be the primary key of its own relation.

What is 3NF and transitive dependency?

What is a transitive dependency maven?
Maven Dependency Tree Transitive dependency means that if A depends on B and B depends on C, then A depends on both B and C. Transitivity brings a very serious problem when different versions of the same artifacts are included by different dependencies. It may cause version mismatch issue in runtime.
When is a transitive dependency not a primary key?
A transitive dependency therefore exists only when the determinant that is not the primary key is not a candidate key for the relation. In the items table we have been using, for example, the distributor is a determinant but not a candidate key for the table. (There can be more than one item coming from a single distributor.)
Which is an example of a transitive verb?
A transitive verb has to transfer the action to an object, either someone or something. In a sense, a transitive verb affects something else. So one way of identifying a transitive verb is to check if the sentence makes sense without the direct object. I kicked the ball.
