Study Notes

Software Application Domains

System Software, Application Software, Embedded Software, and AI Software are primary categories.
Application examples include Banking, Government, Manufacturing, Education, and Medicine.

Digital Transformation

Encompasses the change to digital technologies in various fields.
Examples include social networking platforms (e.g., Instagram, LinkedIn) and innovations in smart agriculture and online banking.

Real World Software Development

Involves formal business contracts and team collaboration rather than individual efforts.
Requires user-friendly interfaces and comprehensive documentation.
Software must handle complexity, security, and rigorous testing for reliability.

Challenges in Software Development

Software development is not traditional manufacturing, focusing on engineering costs instead of production.
Software maintenance presents unique difficulties due to custom-built nature and potential undetectable failure causes.

Quality of Software

Key attributes include correctness, timeliness, robustness, reliability, adaptability, reusability, interoperability, efficiency, user-friendliness, portability, security, and efficacy.

Factors Making Software Development Difficult

User expectations, communication issues, and the "mythical man-month" dilemma affect project outcome.
Complexity, novelty, and various reliability and interface requirements pose additional challenges.

Software Development Life Cycle (SDLC)

Comprises several phases: Requirements Gathering, Planning, Analysis and Design, Development, Testing, Deployment, and Maintenance.
The SRS (Software Requirements Specification) document is created during requirements gathering for clarity among team members.

SDLC Models

Waterfall Model: Follows a linear sequence of phases but does not adapt well to changes; testing is only at the end.
Incremental Model: Breaks down development into increments, allowing for earlier delivery of functionalities and evolving requirements over time.

Advantages of Incremental Model

Provides customer value with each increment, allowing system functionality availability at earlier stages compared to traditional models.
