Test: System Design - 2 - Software Development MCQ

System Maintenance is not a phase of the SDLC. The correct phases are System Analysis, System Design, System Testing, and System Maintenance.

Evaluating project feasibility is an activity performed during the system planning phase to determine whether the project is technically and economically viable.

System analysis is the phase of the SDLC where user requirements are identified and documented.

Data Flow Diagrams (DFDs) are used in structured analysis to model system requirements and illustrate the flow of data within the system.

In a Data Flow Diagram (DFD), a process symbol represents the transformation of data from input to output.

An Entity-Relationship Diagram (ERD) is an example of a structural model used in system design to represent the relationships between entities in a database.

System sizing is performed during system design to determine the hardware and software requirements for the system.

A well-designed system has low coupling (minimal dependencies between components) and high cohesion (components within a module are closely related).

Interface design in system design focuses on designing the user interface of the system.

Use Case Diagrams consist of actors, use cases, and relationships. Classes are not directly represented in Use Case Diagrams.

Singleton is an example of an architectural pattern used in system design to ensure that only one instance of a class exists.

System integration testing is performed to test the interactions and behavior of the system as a whole.

Using prototyping during system development can help reduce development time by quickly building and evaluating prototypes.

Agile software development methodologies prioritize working software over extensive documentation.

Waterfall software development methodology typically involves limited customer involvement during the development process, leading to potential mismatches between customer expectations and the final product.
