<aside> 📌 This document is to manage the various Entity Relationship Diagrams (ERDs) that are applicable to your Salesforce environment.

An ERD, also known as a data model, is a graphical representation of an information system. It shows the relationships among people, objects, places, concepts, and events in that system. It is a logical model that conveys the functional structure of data. In Salesforce ERDs, entities typically map to an object in the Salesforce database.
When you begin building out your ERD, I recommend checking out the Salesforce Data Model Notation guide on **Architect Salesforce.** This will give you a great overview and starting point.
Cardinality indicates the relative numbers of occurrences on each side of the relationship. In the notation, the ends of a relationship line indicate the cardinality of the relationship on that end. A crow's foot on an end indicates that many entity occurrences on that end can relate to each occurrence on the opposite end. The lack of a crow's foot on an end indicates that at most one entity occurrence on that end can relate to a given occurrence on the other end.
