An entity Relationship Diagram is a visual depiction of how entities in a system relate to each other. It is used to illustrate the different types of relationships between entities, such as employees and their team members or customers, and the products they purchase. ERDs are commonly used to create database models by defining tables in terms of their attributes and the relationship between those attributes. Furthermore, the ERD illustrates the various entities that exist within the system and how they may interact with one another through relationship links. It is commonly used by database designers to show how different components of a database connection to each other.
