Automated Teller Machine (ATM) On An Automated Teller ✓ Solved

Automated Teller Machine (ATM) On an automated teller

On an automated teller machine (ATM), the customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smart card with a chip that contains a unique card number and some security information such as an expiration date or card verification value code (CVVC). When using an ATM on networked banks, customers can access their personal or business bank accounts in order to make cash withdrawals and check their account balances. For this assignment, consider cash withdrawal transactions from your favorite ATM machine. Write a four to five (4-5) page paper in which you:

  • Delimit the ATM problem by creating a problem diagram using Visio or an equivalent such as Dia. The diagram must show system components that are relevant to the problem of withdrawing cash.
  • Write one (1) paragraph that describes the use and meaning of the problem diagram components.
  • Create two (2) Structured Analysis and Design Technique (SADT) diagrams to document the activities and data involved in the transactions stated above using Visio or an equivalent such as Dia.
  • Write one (1) paragraph that describes the use and meaning of the SADT diagram components.
  • Provide three (3) possible scenarios of interaction between you and the ATM through a few message sequence charts.
  • Create one (1) UML diagram for each scenario, from Question 5, to show the interactions.
  • Create one (1) state machine diagram for the ATM that covers the scenarios you have identified in Question 5 using Visio or an equivalent such as Dia.
  • Write one (1) paragraph that describes the use and meaning of the state machine diagram components.

Use at least three (3) quality resources in this assignment. Your assignment must follow these formatting requirements: 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.

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 Visio or an equivalent such as Dia. The completed diagrams / charts must be imported into the Word document before the paper is submitted.

Paper For Above Instructions

Automated Teller Machines (ATMs) have revolutionized the way banking services are delivered, making it possible for customers to access their funds conveniently and securely. In this paper, we will explore the ATM's operations during cash withdrawal transactions, utilizing various technical documentation methods such as problem diagrams, Structured Analysis and Design Technique (SADT) diagrams, message sequence charts, and state machine diagrams to delineate the processes involved.

Defining the ATM Withdrawal Problem

The primary problem associated with an ATM cash withdrawal process involves the interactions between the customer, the ATM, and the banking network. To visually represent this problem, a problem diagram can be created that depicts the components involved. These components typically include the ATM interface (both hardware and software), the customer represented by their ATM card, security measures like the PIN (Personal Identification Number), the connection to the bank’s central database, and error handling mechanisms. The diagram illustrates how these components interact during a cash withdrawal process, highlighting the flow of information and ensuring that the ATM operates efficiently.

SADT Diagrams for ATM Transactions

Structured Analysis and Design Technique (SADT) diagrams provide a method for documenting the activities and data involved in ATM transactions, in this case, cash withdrawal. Two SADT diagrams can be developed: one representing the high-level functions involved in the withdrawal process, such as user authentication, account verification, fund disbursement, and transaction recording. The second diagram can delve into the detailed sub-functions of the chosen high-level process, illustrating specific interactions such as the validation of the PIN and the querying of the account balance. Each component of the SADT diagrams serves to clarify the sequence and relationship between tasks and data handling.

Message Sequence Charts: Customer Interaction with ATM

Message sequence charts can be utilized to explore three potential scenarios of customer interaction with the ATM. The first scenario might depict a successful cash withdrawal, illustrating messages exchanged between the customer and the ATM, such as card insertion, PIN entry, fund request, and dispensing cash. The second scenario could represent a failed withdrawal due to insufficient funds, showcasing error messages and the notification process. A third scenario could illustrate a technical error, where the ATM fails to dispense cash, prompting a notification to the customer and automatic logging of the incident for technical support. Each scenario is then represented in UML diagrams to clearly visualize the interaction flows.

State Machine Diagram for ATM Operations

A state machine diagram for the ATM can be developed to cover the scenarios identified in the message sequence charts. This diagram illustrates the various states the ATM can enter during a transaction (e.g., idle, waiting for card, processing transaction, dispensing cash, error state). Each transition between these states represents a key event in the ATM operation process, such as card insertion or successful transaction completion. The state machine components help in understanding how the ATM maintains operational integrity and responds dynamically to a variety of user interactions.

The Importance of Diagrams in Understanding ATM Functions

Each type of diagram used in this paper serves a distinct purpose in clarifying the functions and interactions within the ATM system. The problem diagram provides a broad overview of the system components at play. The SADT diagrams break down the complexities of ATM transactions into manageable parts, while message sequence charts and UML diagrams illustrate user interactions in a clear and structured manner. Finally, the state machine diagram contextualizes the operational flow of the ATM, emphasizing decision-making requirements. Properly interpreting these diagrams is crucial for software developers, researchers, and engineers, as they aid in the design, implementation, and trouble-shooting of ATM systems.

Conclusion

In conclusion, understanding the ATM cash withdrawal process through various technical diagrams not only simplifies the complexities inherent in banking automation but also enhances communication between stakeholders involved in the development and maintenance of such systems. By effectively utilizing problem diagrams, SADT diagrams, message sequence charts, and state machine diagrams, we can cultivate a more profound comprehension of the operations and interactions within an ATM.
