Key/Value Pairs

By

Definition:

Key/Value Pairs - Any value associated with a key identifying it. In a list of grades, the key 'Bob' may have the value 82 associated with it. The key 'Alice' (who is a better student) may have the value 97 associated with it. Key/value pairs aren't often seen on their own, but rather part of data structures such as associative arrays.
