Explanation:
In any relational database system, every field is related to every other
field. There are three types of relationships that can exist between two fields
One to one A one to one relationship exists when for every value of a there is one and
only one correspondig value of b, and for every value of b there is one and only one
corresponding value of a. One to one relationships are modeled within a single table.
One to many A one to many relationship exists when for every value of a there is one or
more corresponding values of b, and for every value of b there is one and only one
corresponding value of a. One to many relationships require two tables to model.
Many to Many A many to many relationship occurs when for every one value of a there
is one or more corresponding values of b, and for every one value of b there is one or
more corresponding values of a. Many to many relationships actually require three tables
to model correctly.
