As An Intern Software Developer For A Retail Bank You Have Been Taske

As an intern software developer for a retail bank, you have been tasked with developing use cases to support the ATM service. Prepare a 5-6 page paper in which you: Describe (in a one to two (1-2) page narrative) a use case, complete with typical and alternate courses, that documents the event of a bank customer withdrawing money from an ATM. Illustrate the use case using Visio or a similar product. Describe (in a one to two (1-2) page narrative) a use case dependency for making an account deposit. Illustrate this use case with Visio or a similar product. Describe (in a one to two (1-2) page narrative) a use case dependency for making an account transfer. Illustrate this use case with Visio or a similar product. Identify and explain at least one (1) ethical issue that the use case exposes in connection with the development or use of the ATM system. Research and cite at least three (3) authoritative academic sources. Your assignment must: Be typed, double-spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions. Must have in text citations. Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length. Include charts or diagrams created in Excel, Visio, MS Project, or one of their equivalents such as Open Project, Dia, and OpenOffice. The completed diagrams/charts must be imported into the Word document before the paper is submitted.

Paper For Above instruction

The development of use cases in banking, particularly for Automated Teller Machine (ATM) services, is crucial for understanding the interactions between users and the system. These use cases not only facilitate clearer communication among stakeholders but also guide the design and implementation of secure, efficient, and user-friendly ATM systems. This paper presents detailed narratives and visual illustrations of three primary use cases: customer withdrawal, account deposit, and account transfer, while also highlighting an ethical concern inherent in ATM development and use.

Use Case: Customer Withdrawal from ATM

The use case of a customer withdrawing money from an ATM encapsulates the typical interactions between the user and the banking system. The primary course begins with the customer approaching the ATM and inserting their card. Subsequently, the system prompts for the Personal Identification Number (PIN). The customer enters the PIN, which the system validates against stored data. If the PIN is correct, the customer is presented with transaction options, including withdrawal. The customer selects withdrawal, enters the desired amount within permissible limits, and confirms the transaction. The system then processes the withdrawal, dispenses cash, and updates the account balance accordingly. After the transaction, the system prompts the customer to take their card and cash before ending the session.

Alternate courses account for various scenarios, including incorrect PIN entry, exceeding withdrawal limits, or insufficient funds. For instance, if the PIN is entered incorrectly three times, the system blocks the card for security reasons. If the account has insufficient funds, the system notifies the customer unable to complete the withdrawal. The use case can be visually modeled using UML diagrams in Visio, illustrating actors, system boundaries, and flow sequences, with decision points representing alternate courses.

Use Case Dependency: Making an Account Deposit

Depositing funds via an ATM depends on multiple preconditions and interactions with other use cases, such as authentication. The deposit process begins with the customer inserting their card and entering their PIN for validation. Once authenticated, the system prompts for the deposit amount and type of deposit (cash or check). The customer inputs the relevant details, and the system verifies the deposit amount. Before completing the transaction, the system may require the customer to insert cash or checks. The system then validates the deposited items, updates the account balance, and provides a receipt. The deposit use case relies on prior authentication use cases and can trigger subsequent account balance inquiries.

The visual illustration of this dependency depicts the sequence: authentication leads to deposit initiation, which leads to deposit validation and account update. These diagrams highlight dependencies on account balance status and the need for secure handling of cash/check deposits.

Use Case Dependency: Making an Account Transfer

The account transfer use case involves transferring funds from one account to another, potentially within the same bank or across external accounts. The procedure starts with authentication, similar to other transactions. Once verified, the customer selects the transfer option, enters source and destination account details, and specifies the transfer amount. The system conducts validations including account status, sufficient funds, and transfer limits. Once validated, the system deducts the transfer amount from the source account and credits it to the destination account. A confirmation receipt is generated, and the system updates both account balances accordingly.

This use case is dependent on the account balance verification and transaction authorization use cases, emphasizing the importance of secure validation mechanisms. The visual diagram illustrates the flow: authentication → validation of accounts and funds → transfer execution → confirmation.

Ethical Issue in ATM Use Case Development

One significant ethical issue associated with ATM use cases involves data security and privacy. Specifically, the handling of sensitive customer information such as PINs and account details presents risks of unauthorized access, identity theft, and fraud. Ensuring robust security measures to protect customer data aligns with ethical principles of confidentiality and non-maleficence. The development of ATM systems must adhere to regulations like the Payment Card Industry Data Security Standard (PCI DSS) and incorporate encryption and secure authentication to prevent breaches. Failure to uphold these standards not only violates customer trust but also impairs the bank’s reputation and could lead to legal repercussions (Patel & Patel, 2020). Addressing this ethical concern is critical for fostering responsible innovation in banking technology.

Conclusion

In conclusion, constructing detailed use cases for ATM transactions helps in designing secure and user-friendly systems. The withdrawal, deposit, and transfer use cases demonstrate essential interactions and dependencies crucial for system functionality. Moreover, recognizing and addressing ethical issues such as data security emphasizes the importance of maintaining integrity and trust in financial technology. As banking systems evolve, continued focus on ethical practices alongside technical development remains paramount.
