Study Notes
Software Engineering Overview
- Economies of developed nations heavily rely on software, with increasing systems controlled by software.
- Software engineering encompasses theories, methods, and tools for professional software development.
- Software expenditures significantly contribute to the Gross National Product (GNP) of developed countries.
Software Costs
- Software costs can surpass computer system costs, often exceeding hardware expenses.
- Maintaining software is typically more costly than its initial development, especially for long-term systems.
- Emphasis on cost-effective software development is crucial in the industry.
Challenges in Software Projects
- The rising complexity of systems demands quicker delivery and new capabilities, increasing project risks.
- Many companies lack structured software engineering methods, leading to higher costs and reduced software reliability.
Frequently Asked Questions about Software Engineering
- What is software? Refers to computer programs and their documentation, developed for specific or general markets.
- Attributes of good software: Must deliver required functionality, performance, maintainability, dependability, and usability.
- Difference between software engineering and computer science: Software engineering focuses on practical aspects of software production, while computer science is theory-based.
- Key challenges: Managing increasing diversity, reducing delivery times, and ensuring software trustworthiness.
- Cost distribution: Roughly 60% of software costs are for development, and 40% are for testing. Evolution costs can exceed initial development for custom solutions.
- Web impact on software engineering: Introduced software services and facilitated the development of distributed service-based systems.
Types of Software Products
- Generic Products: Stand-alone software marketed to any buyer (e.g., PC software like graphics programs).
- Customized Products: Developed for a specific customer to meet their unique needs (e.g., traffic monitoring systems).
Product Specification
- Generic Products: Specifications are owned by the developer, who decides on changes.
- Customized Products: Specifications belong to the customer, who has decision-making authority regarding modifications.
Essential Attributes of Good Software
- Maintainability: Adaptable to meet evolving customer needs, critical in a changing business environment.
- Dependability and Security: Includes reliability and safety; must prevent unauthorized access and damage.
- Efficiency: Should optimize resource use, ensuring quick responses and minimal waste.
- Acceptability: Must meet user needs for usability and compatibility with existing systems.
Importance of Software Engineering
- Society increasingly depends on reliable software systems; hence efficient methods must be used to ensure quality and trust.
- Utilizing software engineering techniques leads to long-term cost savings compared to ad-hoc programming approaches.
