Chapter 10: Demonstrating Connections Using Entity Relationship Diagrams

An entity-relationship diagram is a graphical representation that is used to visualize the different types of entities that exist within a system. It also shows how these entities are related to each other. It can visually represent the details of an entity by highlighting its various attributes and their types. It is also referred to as an ER diagram. Although ER diagrams can be used to model almost any system, they are commonly used in database design to model the schema. In software engineering, they are used during the planning phase to model different system elements and their relationships.

In this chapter, you will learn how to use Mermaid to generate entity-relationship diagrams. You will learn how to create entities, how to define their attributes, how to add different relationships between entities, and how to label them. You will also learn how to customize your ER diagram by modifying the theme...
