Relationship Diagram. An Entity Relationship Diagram is use to
identify an entity for a company. The main four
entity that have been used are Invoice, Customer, Product, and Companies.
Invoice is the main entity out of the main four that are being used. These
entity are placed into a database table that shows different attributes like
