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. Note: A Lynda.com video training link for Microsoft Visio training is provided on page 1 of this course guide. Prepare a 5-6 page paper in which you: 1. 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. 1.

Illustrate the use case using Visio or a similar product. 2. 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. 3. 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. 4. 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. 5. Research and cite at least three (3) authoritative academic sources.

Paper For Above instruction

The development of ATM (Automated Teller Machine) use cases is essential for understanding and designing secure, efficient, and user-friendly banking systems. This paper provides detailed narratives and visual representations of three critical use cases: cash withdrawal, deposit, and transfer, alongside an exploration of an associated ethical concern. The focus is on modeling these use cases using visual tools like Microsoft Visio, which facilitates clear communication and understanding among stakeholders.

Use Case 1: Cash Withdrawal from an ATM

The cash withdrawal process is among the most common ATM transactions. The primary goal is to allow a customer to withdraw cash from their bank account via the ATM securely and efficiently. The primary actor in this use case is the bank customer, while the ATM system operates as the supporting device.

The typical course begins with the customer inserting their debit or credit card into the ATM. The system prompts for a Personal Identification Number (PIN) for authentication. Once the customer enters their PIN correctly, the system validates the PIN against the banking database. Upon successful validation, the customer is prompted to enter the desired withdrawal amount within available balance limits. After the amount is entered, the system verifies if sufficient funds exist in the account.

If funds are sufficient, the system dispenses the cash, updates the account balance, and provides a transaction receipt. The customer then chooses to end the session, and the system ejects the card, concluding the transaction.

An alternate course occurs if the customer enters an incorrect PIN. The system allows a limited number of attempts before retaining the card for security reasons. Another alternate involves insufficient funds, where the system notifies the customer of the shortfall and cancels the transaction without dispensing cash.

Use Case 2: Making an Account Deposit

Depositing funds via an ATM involves several dependencies and steps. The customer begins by inserting their card and authenticating with their PIN. Once authenticated, the ATM prompts the user to select the deposit function. After selection, the customer inserts the deposit envelope or cash, which is then scanned or counted by the system.

This use case depends on the integration with the bank's core systems to validate and credit the deposited amount accurately. The ATM validates the deposit by reading the cheque or cash, counts the notes, and confirms the deposit amount. The system updates the account balance accordingly. The customer is then issued a receipt confirming the deposit, and the session ends with the card being ejected.

Use Case 3: Making an Account Transfer

Account transfer involves moving funds from one account to another within the same bank or across banks. The user initiates the process after authenticating at the ATM. The system displays options to transfer funds, prompting the customer to input their source account, destination account, and transfer amount.

This use case depends on the bank's core backend systems to validate both accounts' existence and sufficient funds in the source account. Once validated, the system executes the transfer by debiting the source account and crediting the destination account. Confirmation is provided to the customer through the ATM display and a printed receipt, and the session concludes with the card ejection.

Ethical Issue: Data Privacy and Security

One significant ethical concern related to ATM transactions is data privacy and security. The ATM system handles sensitive customer information, including card details, PINs, and transaction data. Ensuring this data is protected against unauthorized access, hacking, or data breaches is essential to maintain customer trust and comply with data protection regulations.

Ethical development mandates implementing robust encryption, secure authentication protocols, and regular security audits. Failure to do so exposes customers to identity theft, financial loss, and erosion of trust in the banking institution. Therefore, ethical considerations extend beyond compliance, highlighting the moral obligation to prioritize customer privacy and safeguard personal data.

Conclusion

The use cases detailed here illustrate vital ATM functionalities that support banking operations effectively. Visual modeling tools like Visio enhance understanding and communication of these processes. Furthermore, addressing ethical challenges like data privacy is crucial in developing trustworthy banking systems. As banking technology continues to evolve, ongoing focus on secure and ethical design remains paramount for success and customer confidence.
