This ER diagram outlines an Inventory Management System with entities like "Product," "Supplier," "Inventory," "Customer," and "Order." Products include attributes such as ProductID, ProductName, ProductDescription, and ProductPrice. Suppliers are identified by SupplierID, SupplierName, and SupplierContact. Inventory tracks product quantities, while Customers are identified by CustomerID, CustomerName, and CustomerContact. Orders contain OrderID, CustomerID, ProductID, Quantity, and OrderDate.
Relationships indicate interactions: Products are supplied by Suppliers, stocked in Inventory, and ordered in Orders. Customers place Orders, creating connections between entities. This system streamlines inventory database, ensuring efficient inventory tracking and order processing from supplier to customer.

About ER diagrams
We often make an entity-relationship (ER) diagram, ERD, or entity-relationship model, in the early stages of designing a database. An ERD is perfect for quickly sketching out the elements needed in the system. The ERD explains how the elements interact. ER diagrams can be shared with colleagues. Their simplicity makes them ideal even for non-technical stakeholders.
