What Is A Mapping Diagram

A mapping diagram can be used to represent a relationship between input values and output values. The figure shows a mapping of the elements of the domain to the elements of the range. Mapping, any formulated way of assigning to each object in one set a particular object in another (or the same) set.

It points out the flow of information between the system and external components. The figure shows a mapping of the elements of the domain to the elements of the range. Mapping cardinality is the maximum number of relationship instances in which an entity can participate.

For example, if you are taking the subway you may see a “map” showing you all the stations along a subway line, but that map will not show all the roads and buildings you may pass along the way.

Mapping diagram shows how the elements are paired. Need a custom math course? A process map visually shows the steps of a work activity and the people who are involved in carrying out each step. Usually, arrows or lines are drawn between domain and range to denote the relation between two elements.
