Inventory and Sales Management DFD models a multi-process system where suppliers feed goods into Receive Goods, which populates Inventory Records and triggers Manage Inventory. Customers initiate Process Sales, which updates Sales Records and decrements inventory via Manage Inventory; managers query Generate Reports to access Product Database, Sales Records, and Inventory Records for operational insights. This architecture demonstrates separation of concerns across procurement, fulfillment, and analytics—critical for retail and e-commerce platforms scaling on AWS. Fork this diagram on Diagrams.so to customize data stores, add AWS services like DynamoDB or RDS, or integrate Lambda functions for real-time inventory sync. The design supports both transactional consistency and reporting workflows without tight coupling between sales and inventory operations.
