How do you draw ER diagram for weigh bridge management?

Answer 1

To draw an ER diagram for a weighbridge management system, identify the key entities such as Vehicle, Weighbridge, Transaction, and Driver. Define the relationships between these entities, such as a Vehicle being associated with multiple Transactions and each Transaction linked to a specific Weighbridge and Driver. Include attributes for each entity, like Vehicle ID, Weight, Date, and Driver Name. Finally, use standard ER diagram symbols to represent entities, relationships, and cardinalities to illustrate how these components interact within the system.
