Software Design UNIT-I Quiz

Behavioural and Non-Behavioural Requirements

• Behavioural requirements encompass inputs, outputs, and I/O processes.
• Non-behavioural requirements include aspects such as reliability and efficiency.

Software Design: UNIT-I

• Covers cohesion and coupling classifications, essential in assessing software architecture.
• Distinguishes between function-oriented design (focused on functions) and object-oriented design (centered on objects).
• Highlights user interface design as a critical component impacting user experience.
• Software reliability involves understanding failures and faults alongside reliability models.
• Key reliability models include Logarithmic Poisson Model and Calendar Time Components for reliability allocation.

Transition from SRS to SDD

• Design is a crucial phase in software development, addressing how to create functional and dependable software systems.
• The primary aim is to provide a solution to the problem detailed in the Software Requirements Specification (SRS).
• Effective design reduces the gap between specifications and actual coding outcomes.
• Two primary design types exist:
  • Conceptual Design: Focuses on what the system should do; presented to customers.
  • Technical Design: Details how the system will be built; shared with system builders.

Characteristics of Good Design

• Correctness and completeness are vital traits for effective software design.
• Understandability ensures that the design can be easily interpreted.
• Maintainability facilitates code maintenance and updates.
• Durability ensures the design withstands changes and time.
• Utility reflects the design's usefulness in real-world applications.
• Directly Codeable designs minimize obstacles in translating to code, though this is challenging to achieve.

Design Document Evolution

• A finished design document is a dynamic artifact, not a final product.
• The initial design is informal and undergoes refinement through multiple phases, adding detailed information as development progresses.
