Assignment 2 Use Casesdue Week 6 And Worth 200 Pointsas An Intern

Assignment 2: Use Cases Due Week 6 and worth 200 points. 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.
• 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 use of Automated Teller Machines (ATMs) has revolutionized banking services by offering customers convenient, 24/7 access to their bank accounts. Developing comprehensive use cases for ATM functionalities is critical for understanding system requirements, identifying potential issues, and ensuring secure and ethical operation. This paper presents detailed narratives and diagrams for specific ATM use cases: money withdrawal, account deposit, and account transfer, along with an exploration of associated dependencies and ethical considerations.

Use Case: Customer Withdrawal from ATM

The process of withdrawing cash from an ATM involves multiple steps that ensure security, accuracy, and user satisfaction. The primary use case begins when a customer approaches the ATM and initiates a withdrawal request. The typical course involves inserting a bank card, entering Personal Identification Number (PIN), selecting withdrawal, specifying the amount, and collecting cash along with a receipt. The system validates the card and PIN, checks sufficient account balance, dispenses cash, and updates the account balance accordingly.

Alternate courses address various scenarios such as incorrect PIN entry (with a limit on attempts), insufficient funds, or machine errors. For example, if the customer enters an incorrect PIN three times, the system blocks further attempts and ejects the card, prompting the customer to contact the bank. If funds are insufficient, the system notifies the user and cancels the transaction without dispensing cash. Error handling at each step ensures system robustness and user safety.

The accompanying use case diagram illustrates interactions between the customer, ATM system, bank database, and cash dispenser. It captures the flow of events, decision points, and exception handling to provide a comprehensive visual overview of the withdrawal process.

Use Case Dependency: Making an Account Deposit

Depositing funds into an account through an ATM depends on prior authentication and account verification processes. The deposit use case begins with the customer inserting their card and entering PIN, then selecting the deposit option. The system prompts the user to insert cash or checks, which are scanned or counted by the ATM’s internal mechanisms. The system validates the deposit data and updates the account balance accordingly.

Dependencies include the need for secure connection to the bank database, verification of deposit amount, and validation of deposit type. The deposit process relies on previous authentication use cases, as access to account data is required. The use case diagram showcases the sequence of interactions, including customer actions, system validation steps, and database updates.

Use Case Dependency: Making an Account Transfer

Transferring funds between accounts within the same bank necessitates secure authentication, account verification, and precise transaction execution. The customer initiates the transfer by logging into their account via ATM, navigating to the transfer option. The system prompts them to enter source and destination account numbers and transfer amount. After validating their authorization and the existence of accounts, the system deducts the transfer amount from the source account and credits it to the destination account.

This process depends on the prior use cases of login and account verification, ensuring that only authorized transactions occur. The dependencies also involve real-time validation of account statuses, sufficient funds, and transaction recording for audit purposes. The associated diagram visually models the sequence, dependencies, and exception handling such as failed validation or insufficient funds.

Ethical Issue in ATM Use Cases

One significant ethical issue exposed by ATM use cases is data privacy and security. Unauthorized access to customer information, such as PINs, account numbers, or transaction histories, poses risks of identity theft and financial fraud. System vulnerabilities may be exploited by cybercriminals to intercept sensitive data or manipulate transaction records. Moreover, ethical concerns arise from ensuring equitable access to ATM services, preventing discrimination against users with disabilities or those without access to banking infrastructure. Developers and banks bear ethical responsibilities to implement robust encryption, security protocols, and inclusive design principles to protect customer data and promote fair access.

Conclusion

Developing detailed use cases for ATM services enables better understanding of system requirements, security considerations, and potential pitfalls. The narratives, complemented by illustrative diagrams, provide a structured approach to designing reliable, secure, and user-friendly banking systems. Addressing the ethical issues through comprehensive security measures and inclusive design upholds the integrity and trustworthiness of banking operations, ultimately benefiting both financial institutions and their customers.
