Following is an ER diagram for a Bank Management System. In this ER diagram entities are represented by square boxes, with their attributes listed inside oval shapes. Five key entities are depicted: the Bank, Bank Accounts, Customer, Employee, and Transaction. The ER diagram illustrates the relationships between these entities. This includes the association between Bank Accounts and Employees, and the association between Customers and their accounts. Along with this, every transaction within a Bank Account is recorded through the Transaction entity, enabling a comprehensive tracking of account activity.
