Defining an Entity and its attributes
In this section, you will learn about entities and how they are represented in an entity-relationship diagram. You will also learn about the syntax of defining an entity in Mermaid, as well as how to add attributes to an entity.
One big advantage of using Mermaid to create an ER diagram, for you as an author, is that you only provide data about entities; you do not need to take care of their layout. You don't have to worry about the positioning of the individual entities and relationship edges while rendering the diagram; Mermaid takes care of this for you. You just need to define the entities and focus on how they are structured using a well-defined syntax. Then, Mermaid will render a nice-looking diagram for you based on your inputs. First, let's understand how an entity is represented. Then, we will have a closer look at the syntax for defining an entity in Mermaid.
