UML diagram types: structure and behavior diagrams (14 examples)
In this video, we’ll give you a summary and an example of each UML diagram type.
Chen notation vs Crow's foot notation (ER diagram)
This time we’re going to compare Chen notation with Crow’s Foot notation. These are the two most popular ways to create entity-relationship diagrams.

UML Sequence diagram example: Library management system
Our example for today is a sequence diagram to describe how a library management system operates.
UML Class diagram example: Restaurant management system
In this video, we’re going to design a class diagram for a restaurant management system.
ER diagram Crow's foot example: Hospital management system
In this video, we’re going to design an entity-relationship diagram for a hospital management system.
ER diagram Crow's foot example: Online shopping system
Today we’ll demonstrate how to design an online shopping system. We’ll use an entity-relationship diagram and Crow's Foot notation.
