1. Introduction

This is an example of UML case diagram for inventory management. Case diagrams are good for illustrating dynamic behaviors between actors within a system, by simplifying the view of the system. A use case diagram can summarize the details of your system's users (also known as actors) and their interactions with the system in the Unified Modeling Language (UML). You'll need a collection of specialized symbols and connectors to construct one. A good use case diagram can assist your team in discussing and representing:

Interactions between your system or application and people, organizations, or external systems. Goals that your system or application assists those entities (sometimes referred to as actors) in achieving your system's capabilities".
