A Complete Guide to Database Diagram Symbols

A complete guide to the symbols shown in entity-relationship diagrams (ERDs). Although data modeling became a necessity around the 1970s, there was no standard way to model databases or business processes. Many solutions were proposed and discussed, but none were widely adopted. Peter Chen is credited with creating the ER (entity-relationship) model, which introduced a way of mapping data model elements (which would become database elements) and their relationships. This model can serve as the diagram as well as the documentation for a database project.
