People without lots of technical knowledge can typically understand this sort of diagram easily, and that is one among its main benefits. It can help iron the design ahead of the development team has now devoted to a design.

To comprehend this more fully, they are some quick definitions:
* Entity: An entity describes an item, typically somebody, place, or thing. By way of example, a car could possibly be an entity on an auto dealership.
