ISE102: Introduction to Software Engineering Prototype and Software Solution Assessment 2

Assessment 2

Learning Outcomes

The Subject Learning Outcomes demonstrated by successful completion of the task below include:

a) Identify user requirements in computer-driven software applications.

c) Apply software programming methodologies including objectoriented programming (OOP) paradigms to build software solutions.

d) Test and validate software solutions thatsatisfy project requirements.

Assessment Task

In this assessment, your group will be required to demonstrate an understanding of object-oriented programming principles and knowledge using programming language features you have learnt in Modules 5 to 8. Please refer to the Task Instructions for details on how to complete this task

Case Study

You are to develop a banking software application for a major bank in NSW Australia. Your banking applications will include four major modules which will be addressed in Assessment 2 and 3 respectively. The modules will include ‘signup, login, deposit and withdraw’. In Assessment 2, you are to create signup and login modules. The sign-up collects information from the user while the login cross verifies the input with the registered information. The login will let the verified user access further banking operation that will be developed in Assessment 3. Program description: To develop this complete application of login and signup, you will need to develop appropriate methods for Bank class.

Task 1: Login Module

Create a Bank class with the name (Bank) which can handle login and signup. For Login: For task 1, we advise using Username: Joe.Doe and Password: Password123 as testing data for login attempts. They may be initialized as a verified dummy user in the Bank object. You need to create a “login” method which takes two arguments – username and password - which will then be cross verified by the program. If user credentials do not match, it shows an error and requests the user to re-enter the credentials. If credentials are verified, then the application will take the user to the main screen (See samples 1 and 2). You can restrict the password attempts to 3 or leave it infinite. For security reasons, it is often necessary to limit the password attempts to 3 or less. In this part of assessments, there is no special requirement for username or password.

Task 2: Signup

This method will ask the user to register him/herself by providing personal information in the form field or attributes which are Username, Email, Age, Phone, and Password. 1. For this assessment there is no restriction on form fields or attributes. 2. When all given fields provided by the user are entered, you can validate the sign-up by trying to log in using the same credentials. 3. If any field is empty in the signup process, your software must prompt the user to enter all details correctly. 4. Once you can sign up and login using your software program, you can provide evidence of code and all screenshots to demonstrate your work. 5. For advanced students, you can try to use a List to keep more than one user credential (but there is no extra mark associated with this task).

Brief Summary of Assessment Requirements

Assessment 2 is designed to evaluate students’ understanding and application of object-oriented programming (OOP) concepts through the development of a banking software application. The assessment focuses on identifying user requirements, applying programming methodologies, and testing software solutions to meet project specifications.

Key Pointers to Be Covered in the Assessment

• Identification of user requirements for a banking application
• Application of OOP principles using a suitable programming language
• Development of core banking modules: Signup and Login
• Implementation of a Bank class with appropriate methods
• Validation and testing of user input and credentials
• Error handling and user feedback for incorrect or incomplete inputs
• Submission of source code and screenshots as evidence of functionality

The case study requires students to build a banking system for a major bank in NSW, Australia. In Assessment 2, students are specifically responsible for implementing the signup and login modules, which will later support further banking operations in Assessment 3.

Academic Mentor’s Step-by-Step Guidance Approach

The academic mentor supported the student through a structured, step-by-step process to ensure alignment with the assessment criteria and learning outcomes.

Step 1: Understanding the Case Study and Learning Outcomes

The mentor first explained the real-world context of the banking application and linked it to the subject learning outcomes. Emphasis was placed on understanding user requirements and how OOP concepts can model real banking operations.

Step 2: Designing the Bank Class

The mentor guided the student in creating a Bank class, explaining its role as the core component responsible for handling signup and login operations. The concept of encapsulation was highlighted while defining attributes and methods.

Step 3: Developing the Login Module

For the login task:

• The mentor explained how to initialize a dummy verified user (Username: Joe.Doe, Password: Password123) for testing purposes.
• The student was guided to create a login() method that accepts username and password as arguments.
• Logic for credential verification, error messages, and retry attempts was implemented.
• Security considerations such as limiting login attempts were discussed.

Step 4: Implementing the Signup Module

For the signup task:

• The mentor assisted in defining user attributes such as Username, Email, Age, Phone, and Password.
• Input validation was explained, ensuring no field is left empty.
• The student was guided to verify successful signup by logging in with the newly created credentials.
• Optional enhancement using a list to store multiple user credentials was discussed for advanced understanding.

Step 5: Testing and Validation

The mentor emphasized testing all scenarios:

• Correct and incorrect login attempts
• Empty fields during signup
• Successful signup followed by login

Screenshots and code outputs were prepared as evidence to demonstrate correct functionality.

Outcome Achieved

By following the mentor’s guidance:

• A fully functional signup and login module was successfully developed.
• The Bank class effectively handled user authentication.
• Input validation and error handling were correctly implemented.
• The software met all stated assessment requirements and task instructions.
• Supporting code and screenshots clearly demonstrated the working solution.

Learning Objectives Covered

Through this assessment, the student successfully demonstrated:

• Identification of user requirements in a software application
• Application of object-oriented programming principles
• Use of programming methodologies to build functional modules
• Testing and validation of software solutions
• Logical problem-solving and real-world application of programming concepts
