Study Notes
Software Engineering Defined
- Software is a collection of executable code, libraries, and documentation.
- Engineering focuses on developing products using scientific principles.
- Software engineering applies a systematic, disciplined, and quantifiable approach to software development, operation, and maintenance.
- It's a collection of past experience arranged into methodologies and guidelines.
- Software engineering principles are essential for large software products to manage complexity and achieve cost-effective quality.
Addressing Complexity in Software Development
- Abstraction simplifies a problem by omitting irrelevant details, focusing on relevant aspects for a specific purpose.
- Decomposition breaks down a complex problem into smaller, independent subproblems that can be solved individually and then combined for a complete solution.
- Effective decomposition minimizes interactions between subcomponents to ensure separate problem solving and avoid complexity.
The Importance of Software Engineering
- Changing user requirements and environments make software engineering necessary for managing evolving needs.
- Large software projects require systematic engineering principles for successful development, similar to the need for engineering to build complex structures.
- Scalability is crucial for handling changing business needs and growth in software systems, which would be challenging without well-defined processes.
- Cost optimization is achieved through efficient software development, especially as hardware costs decrease.
