Software System for Automatic Teller Machine (ATM) A user, who wishes to withdraw money, provides the system with the bank card and his/her PIN. Using the information provided by the user, the system will contact with the bank to determine if the PIN of the user is correct. If the PIN is correct, the system will ask how much money the user wants to withdraw. Using the amount provided by the user, the system will check if the amount of money in the ATM is enough. If it is enough, the system will contact with the bank to determine if the amount of money in the users account is enough. If it is enough, the system will provide the money to the user and notify the bank to update the users account. Otherwise, the system will tell the user why it can not be done and then ask the user if he/she would like to input a new amount. If the user refuses, the system will return the card to the user. Otherwise, the system will repeat the process above to complete the new transaction. (4.1). Draw a UML sequence diagram. (4.2). Draw a UML activity diagram. (4.3). Draw a UML class diagram to model the software system for ATM. For each class, you only need to give it a name. Its attributes or methods are not needed.
