Sequence diagram: This diagram shows the flow of actions between different parts of the system as a whole. This shows the sequence of events that take place internally to accomplish a required function or use case. Activity diagram:
This diagram shows specific actions as they take place internally step by step. This shows actions
as well as decisions the system makes based on each action or input. This diagram also shows specific symbols to describe the type of action that is carried out by the system. Examples are rectangles for actions, diamonds for decisions, and arrows for transitions. This represents the flow as it takes place within the system. These steps are outlined in order as they take place in the system. The diagrams show the ATM sequence and the activity diagram. This outlines the actions taking place within an ATM system as a customer attempts to withdraw cash from the ATM. The use case includes the customer, the ATM system, and the bank. This process is initiated by entering their ATM card into the ATM and entering their unique PIN. The ATM then verifies the correct PIN was entered by the customer. The ATM then checks the bank’s system to retrieve the customer’s current account balance. If the amount requested is less than or equal to the requested
amount the cash is dispensed to the customer. The ATM then generates a receipt and prints that receipt to the customer. The activity shows a more detailed depiction of the process taking place within the ATM. Begins the process by inserting the customer's ATM card and entering their PIN. The ATM then verifies PIN followed by checking banks system for current balance. The system will then make sure
sufficient balance before dispensing cash. If there is insufficient balance a receipt with a current balance is generated otherwise the case is dispensed followed by printing transaction receipt. When the user enters the amount to withdraw, the ATM should send a transmission to the bank. The transmission should then be used by the bank’s system to verify the amount is available and then send that balance to the ATM. If the balance is greater than or equal to the amount requested, then the ATM will dispense the cash. The following step will be to generate and print a receipt.
