Study Notes

Scalability, Cost, and Dynamic Nature

Scientific and engineering principles in software processes enable efficient scaling of existing software over recreation.
The hardware industry has reduced computer and electronic hardware costs through mass production, but software costs remain high without a proper process.
Software's evolving nature necessitates continuous enhancements, influenced by the user environment, showcasing the importance of software engineering.

Characteristics of Good Software

Evaluation criteria for software includes operational efficiency, transitional capabilities, and maintenance ease.
Software quality is judged based on what it delivers and user-friendliness, ensuring it meets operational standards effectively.

Definition and Scope of Software Engineering

Software engineering merges software with engineering disciplines to produce reliable software products.
Software encompasses executable code, libraries, and documentation, designated for specific requirements as 'software products'.
Engineering is defined by the application of systematic, scientific methods for product development.
IEEE characterizes software engineering as a systematic, disciplined, and quantifiable approach to software development, operations, and maintenance.

Importance of Software Engineering

For large software product development, engineering principles are crucial for achieving high-quality outcomes efficiently.
Developing large-scale software increases complexity exponentially, necessitating software engineering to manage this challenge.
Software engineering techniques include:
- Abstraction: Simplifies problems by ignoring irrelevant details and focusing only on essential aspects.
- Decomposition: Breaks down complex problems into manageable smaller parts to solve independently, minimizing component interdependencies.

Need for Software Engineering

Rapid changes in user requirements and software environments drive the necessity for structured software engineering practices.
As software scale grows, a scientific approach is essential for effective design, akin to constructing a house compared to a wall.
