It can help iron out the design prior to the development team has recently focused on a design. It may also be utilized to code the database as well as communicate regarding the nature in the database with a variety of those who are involved in the project.
To comprehend this more fully, they are some quick definitions:
* Entity: An entity means a physical object, typically an individual, place, or thing. For example, a vehicle could be an entity to have an auto dealership.
