This Inventory Management System ER Diagram depicts a system for inventory management. Each inventory manager manages inventory and controls payments using attributes such as User Name, User ID, and Responsibilities. Each inventory item has quality, Item ID, and Inventory ID characteristics. When a customer (with the attributes ID, Name, and Email) places an order, the system processes the payment. In the early phases of designing a database, we frequently create an entity-relationship (ER) diagram, ERD, or entity-relationship model. An ERD is ideal for quickly sketching out the system's elements. The ERD describes how the components interact with one another. ER diagrams can be distributed to colleagues. Because of their simplicity, they are suitable even for non-technical stakeholders.
