, Question 1
1.1 Similarity and Difference Between Classes and Use Cases
Similarity: Both classes and use cases are fundamental concepts in object-oriented analysis and
design, serving as essential components in Unified Modeling Language (UML) to model and
organize system functionalities and data structures.
Difference: The primary difference lies in their purpose: classes represent the blueprint for creating
objects, defining their properties and behaviors, while use cases describe the interactions between
users and the system, focusing on what the system should do from the user's perspective
1.2 Types of Questions in User Interviews
When conducting interviews with users to understand business functions and rules, two types of
questions can be asked:
Open-Ended Questions: These questions encourage users to provide detailed responses and
insights about their needs, experiences, and expectations. For example, "Can you describe a typical
day using this system?" This type of question helps gather qualitative data and understand user
workflows.
Closed-Ended Questions: These questions are designed to elicit specific information, often with a
limited set of responses (e.g., yes/no or multiple-choice). For instance, "Do you find the current
system easy to use?" This type of question helps quantify user opinions and can be useful for
statistical analysis.
1.3 System Design Question
In system analysis, the primary focus is on answering the "what" question, which pertains to what
the system should accomplish. In contrast, system design answers the "how" question, detailing
how the system will be constructed to meet the identified requirements. This includes
considerations of architecture, technology choices, and implementation strategies to ensure that the
system effectively fulfills its intended functions.

2.1 Use Cases on Car Manufacturer Websites
As a potential buyer visiting the websites of car manufacturers like VW, BMW, Mercedes, and
Toyota, the following use cases aligned with my goals:
• Vehicle Configuration Tools: Customizing a vehicle's features, colors, and packages to
match personal preferences.
• Online Financing Options: Accessing financing calculators and loan options to understand
payment plans and affordability.
• Inventory Search: Browsing available models and their specifications, including features,
prices, and availability at local dealerships.
• Test Drive Scheduling: Booking appointments for test drives directly through the website.
• Customer Support Chatbots: Utilizing AI-driven chatbots for immediate answers to
questions regarding models, features, and services.

without visiting a dealership.

influence purchasing decisions.
