Assessment item 2

ITC508 – Case Study 2

Collin’s ATM System

Collin’s ATM Bank requires an ATM System to facilitate customers in their daily

banking activities. The system should have a card reader to read ATM cards, a

keypad, a display, a cash dispenser, a printer to print transactional details, and a

chute to deposit cheques/cash.

The key requirements for ATM system are listed below.

Service’s for customer

It is compulsory that the ATM system will serve one customer at a time.

Card Recognition by the respective bank

Upon arrival, customer needs to insert their ATM card in the card reader and wait till

their card is recognized. If the card is not recognized within 5 seconds, a timeout

error will be displayed. Thereafter, the customer needs to re-insert the card.

Pin Verification

Upon successful card recognition, customer needs to enter their 4 or 6 digits pin,

which will then be verified by the respective bank to grant authorisation to customer’s

account. If the pin is incorrect, customer will have three chances to re-enter the

correct pin; otherwise the card will be captured by the ATM machine.

Account Selection

Once the pin is verified, customer can select their account (e.g. Savings, Credit and

Super Saver).

Account Transaction(s)

Upon account selection, the main menu will be displayed which allows a customer to

perform the following transactions, if required.

 Customer can only withdraw if he/she has sufficient funds in their account.

 Customer can deposit any amount anytime in their account.

 Customer can check account balance without any hassle.

 Customer can transfer money into another account, inside or outside the

back.

 Customer can print the transaction history.

After completing one transaction, customer can either go back to the main menu and

select other transaction OR finish the current transaction. In case the customer

wants to finish their transaction, the system ejects the ATM card.

Generate Receipt

For the latest transaction, the system should generate a receipt.

Report Generation The system should facilitate the respective bank to generate daily, weekly, monthly, quarterly and annual reports to track the inflow and outflow of cash from a respective back. Note In case of missing information, kindly make suitable assumptions and mention them in your assignment.

3. Draw a UML domain model class diagram for all systems in your chosen case study. Be as specific and accurate as possible, given the information provided. If needed information is not given, make realistic assumptions.
4. For each of the five design activity of SDLC, list and briefly describe some specific tasks required for each design activities (i.e., describing the environment, designing application components, user interfaces, the database, and software methods.

Rationale

This assessment tasks covers the fundamental concepts of object modeling, use cases, dynamic models and has been designed to ensure that you are engaging with the subject content on a regular basis. The purpose of the assessment task is to strengthen the student's skill in developing a detailed OO design using UML notation, based on a set of user requirements. More specifically it assess your ability to:


• Apply the concepts of object orientation methodology (Learning outcome 1).
• Analyse system requirements to determine the use cases and domain model of the problem domain (Learning outcome 3).
• Create class diagrams and dynamic models with UML notations (Learning outcome 4).
• Perform modeling of various aspects of systems to construct quality diagrams from a case study (Learning outcome 6).

1. Functional and Non Functional Requirements
1.1 Functional Requirements
The major functional requirements of the ATM system are those requirements that are directly associated with the system functional specifications to the customer. These major functional requirements are as follows.
· If there is no card swapped in ATM then ATM must be with the display with initial welcome message to all the customers.
· If the card is not properly entered or swapped in card reader then e
or message is displayed with indicating to re-insert the card into the card reader.
· The card reader of ATM accepts the customer card and determine the customer bank account number within 5 seconds. If 5 second expires and card is not recognized then time out e
or message is displayed.
· if the ATM has no cash but it should accept the customer card and when customer process to dispense the cash it will display the e
or message.
· ATM should verify and validate the customer ATM card then process to ask the PIN (Personal Identification Number) of customer ATM card.
· Once the card is read and verified then ATM should display to enter the PIN.
· A keypad attached with ATM machine accepts the customer digit punch and verify the same with bank code and bank server.
· If entered 4 to 6 digit PIN is verified to wrong three times by reentering with ATM display message of inco
ect PIN and Re-Enter PIN again 3 times then card is being captured by ATM and a message of e
or is displayed to display of ATM.
· If Entered 4 or 6 digit PIN is verified to co
ect by bank server then ATM opens a menu with option to select account type such as Saving, Credit, Cu
ent and Super Saver.
· The customer selects the account type and ATM displays a menu containing “Withdraw”, “Deposit”, “Check Account Balance”, “Transfer Money”, “Print Transaction History”.
· Customer selects any option as per requirement and ATM system open the window as per the selected option.
· Customer selects withdraw option and ATM displays to enter amount. Customer type amount by punching digits from keypad.
· Bank server verifies amount and if found cu
ent balance is equal or more than amount selected by cu
ent card customer then dispense the cash through cash dispenser otherwise displays the E
or message on display screen that no sufficient balance and go to main menu for customer to select an option.
· After Withdrawal ATM display message “Transaction Completed” along with message for other transaction by Yes or No.
· If customer selects Yes then ATM opens main menu otherwise ejects the card and print the receipts for latest transaction.
· ATM now goes to ideal state by displaying welcome message for accepting the card through card reader to customers.
Above all are the major functional requirements of the ATM machine. Beside these core functional requirements some of the other functional requirements are also needed for the ATM system (Shoval, 2007). These functional requirements are as follows.
· The card should be ejected if the customer does not do anything till the elapse of 10 seconds.
· When cash is dispensed by cash dispenser and customer does not take the cash then cash is taken back into the cash dispenser after 20 seconds
· If there is no printing paper in printer of ATM then ATM display the balance amount of customer account when customer selects the balance enquiry.
· The main menu also display the option for Report generation and when customer selects this then option for weekly, monthly yearly is displayed to be selected and system must confirm after customer select option.
1.2 Non Functional Requirements
There are many non functional requirements of the ATM system. These non functional requirements are detailed as follows.
· The ATM system consists of a visual display unit, a cash dispenser, a card reader, a drawer slot for envelop, a printing unit with printing paper role, and a keypad for user interface.
· The ATM system keypad must have the keys of 10 numeric digits starting from 0 to 9, one cancel key, one okay key, and one cancel key button.
· The personal identification number must be entered within 30 seconds when system asks for it.
· The customer must enter the co
ect personal identification number in three attempts otherwise card must be captured after three wrong entry.
· Security level of ATM system must be high with internal components and external environment.
· ATM system can be shutdown automatically when internal soft problem comes into existence and restarted automatically with co
ect state of functioning.
· The envelop drawer must be opened by customer to enter the envelop and after entry it automatically closed.
· The cash dispenser of ATM system can be opened and cash resetting is supported by authorized staff member.
· ATM system internal chamber must be locked for unauthorized opening of cash dispenser etc.
· The printer attached with ATM system can be opened for paper role resetting.
