Use Case Diagram for the online bank system

What is a Use Case Diagram?

A tool is called a Use Case Diagram which is used to create, present, and comprehend the functional requirements for a system. The Use Case Diagram also specifies the particular context of use for the product that is being developed. Because of this, it does not specify the sequence in which the tasks must be finished.

Use Case Diagrams are representations of potential user interactions with programs. A Use Case Diagram also shows many use cases and user types for the system, the ellipses or circles that were utilized to represent the use cases.

A system of software tools and procedures used by banks to manage risk, technology, customer interactions, and cash flow is known as the bank management system. Banks utilize management systems for a variety of reasons, and these systems are in charge of making sure the bank manages itself to increase efficiencies and make better long-term decisions.

The bank management system is used to track information about clients, staff members, and other elements. It is an application that keeps track of a customer's bank account. The customer can do this to open an account, make deposits or withdrawals, and view reports for all accounts in the system.
