Bank Account Management Data Flow is a process that describes how data flows between different entities in a bank’s account management system. The data flow diagram of a bank’s account management system typically includes the following entities: customers, bank employees, bank accounts, and the bank’s database. The diagram shows how data is created, stored, and used by these entities. It also shows how data is transferred between these entities and how it is processed. The data flow diagram is an important tool for understanding how a bank’s account management system works and for identifying potential problems or inefficiencies in the system.
