What is an entity-relationship model?

An entity-relationship model is a visual representation of the relationships between different entities (objects, concepts, or things) in a particular domain or system. The model depicts the various types of relationships between different entities, such as one-to-one, one-to-many, and many-to-many, as well as attributes that describe the entities themselves. The purpose of an entity-relationship model is to provide a clear, intuitive, and organized way to describe the structure of a system or domain, enabling developers, users, and stakeholders to better understand its workings and improve the quality of their decision-making.
