SOFTWEN1 Quiz#1- Midterm

What is software design?

• A process to transform computer system implementation into stakeholder's requirements

• A process to transform stakeholder's requirements into computer code

• A process to transform stakeholder's requirements into suitable form for computer system implementation

• A process to transform computer code into stakeholder's requirements

In a school management system, the design includes a Student Portal, Teacher Portal, Admin Panel, and a Database, with clear connections showing how they interact. This representation is an example of which software model?

• Behavioral Model – showing how the system reacts to events

• Structural Model – showing system components and their connections

• Framework Model – organizing the system into layered styles

• Interface Design – focusing on how users interact with the system

A company is building an online store. The client requests that users should be able to add items to a cart and pay. The developers then create diagrams showing how the website, server, and database will connect, and afterward they begin coding the system in Python. Which sequence of software development activities does this scenario illustrate?

• Construction → Requirements → Design

• Requirements → Design → Construction

• Design → Construction → Requirements

• Requirements → Construction → Design

What is the advantage of high cohesion and low coupling in modular systems?

• Modules are harder to modify

• Increased potential for reuse

• Modules are harder to develop and test

• Modules are harder to understand

In a student information system, the “Student” class includes attributes such as Name, ID, and Course, which can be accessed by other modules. However, the details of how this data is stored in the database (tables, indexes, queries) are hidden. This best illustrates:

• Information Hiding – preventing outside access to sensitive data

• Coupling – reducing dependencies between modules

• Data Abstraction – focusing on essential characteristics of data while hiding storage details

• Component-Level Design – detailing the methods inside a module

What are the aspects of architectural design representation?

• Structural properties, Functional properties, Families of related systems

• Structural Model, Process Model, Functional Model

• Structural properties, Extra-functional properties, Families of related systems

• Structural Model, Framework Model, Dynamic Model

What is the key to any good design in terms of functional independence?

• Error isolation, Scope of reuse, Understandability

• Error isolation, Scope of modification, Understandability

• Error isolation, Scope of development, Understandability

• Error isolation, Scope of testing, Understandability

What is the benefit of modularization in software design?

• Increased system complexity

• Reduced maintainability

• Ease of software testing and debugging

• Higher coupling between modules

A software team is designing a login page for a school portal. They carefully arrange the username and password input fields, add a "Login" button, and include an option to reset forgotten passwords. This situation best illustrates which software design concept?

• Component-Level Design – detailing the inner workings of a module

• Interface Design – focusing on how the user and system interact

• Coupling – measuring how dependent modules are on each other

• Abstraction – hiding the internal details of a process

What is a characteristic of a module with high cohesion and low coupling?

• Strong dependency on other modules

• Tight integration with external systems

• Functional independence from other modules

• Extensive communication with external components
