A relation is in ____________ if an attribute of a composite key is dependent on an attribute of other composite key.
Question
A relation is in ____________ if an attribute of a composite key is dependent on an attribute of other composite key.
Solution
The relation is in Partial Dependency if an attribute of a composite key is dependent on an attribute of another composite key.
Here are the steps to understand this:
-
A composite key is a key that consists of more than one attribute to uniquely identify an entity in a relation.
-
Dependency refers to the relationship between attributes. In this case, one attribute's value depends on the value of another attribute.
-
Partial dependency occurs when an attribute is dependent on only part of a composite key, not the whole key.
So, if an attribute of a composite key is dependent on an attribute of another composite key, it is said to be in Partial Dependency.
