What is an entity-relationship diagram?

Entity-relationship diagrams or ER diagrams are used to showcase the relationships developed between objects or entities in a system. Also known as the entity-relationship model, this type of flowchart is used in various fields such as research, education, business information system, or software engineering.

What are the components of an entity-relationship diagram?

ER diagrams or ERD’s are composed of three main elements: entities, attributes, and relationships.

  • Entities - typically displayed in a rectangle, entities can be represented by objects, persons, concepts, or events that contain data.
  • Attributes - displayed in a circle or an oval, the attributes refer to the characteristics of an entity. They can be categorized as simple, composite, or derived, and an object can have one or multiple attributes.
  • Relationships - illustrate how two or more entities interact with each other. They are displayed as labels placed on the lines connecting the objects.

How do you draw an entity-relationship diagram?

Our templates are easily adaptable to match your work requirements. However, when building your ER diagram, there are a few steps to keep in mind:

  • Identify the purpose - what is the purpose of the erd template you are creating?
  • Identify entities - once you have identified these entities, add them in rectangles.
  • Identify relationships - how are these entities related?
  • Identify attributes - what are the key attributes of the defined entities?
