Study Notes
Professional Software Development
- Software engineering is concerned with theories, methods, and tools for professional software development.
- Economies of all developed nations are dependent on software, and expenditure on software represents a significant fraction of GNP in all developed countries.
Software Engineering Ethics
- Software engineering ethics are concerned with brief introduction to ethical issues that affect software engineering.
- The ACM/IEEE Code of Ethics provides a framework for software engineering professionals to act in a manner that is in the best interests of their client and employer, consistent with the public interest.
Case Studies
- Examples of case studies used in later chapters include weather stations, weather information systems, and digital learning environments.
Software Costs
- Software costs often dominate computer system costs, and maintenance costs may be several times development costs.
- Software engineering is concerned with cost-effective software development.
Software Project Failure
- Increasing system complexity leads to demands for faster delivery, larger systems, and new capabilities.
- Software engineering is concerned with managing these complexities to avoid project failure.
Software Products
- Generic products are stand-alone systems marketed and sold to any customer, such as PC software and CAD software.
- Customized products are software commissioned by a specific customer to meet their own needs, such as embedded control systems and air traffic control software.
Product Specification
- The specification of generic products is owned by the software developer, who makes decisions on software changes.
- The specification of customized products is owned by the customer, who makes decisions on software changes.
Essential Attributes of Good Software
- Maintainability: software should be written to evolve to meet changing customer needs.
- Dependability and security: software should not cause physical or economic damage in the event of system failure.
Software Engineering Code of Ethics
- The Code of Ethics provides a framework for software engineering professionals to act in a manner that is in the best interests of their client and employer, consistent with the public interest.
- The eight principles of the Code of Ethics include acting in the public interest, acting in the best interests of clients and employers, and ensuring products meet the highest professional standards.
Case Study: Weather Station
- The weather station system collects weather data, carries out initial data processing, and transmits it to the data management system.
- The system includes a number of instruments that measure weather parameters, such as wind speed and direction, temperature, and rainfall.
Case Study: iLearn
- iLearn is a digital learning environment with a set of general-purpose and specially designed tools for learning.
- The system is a service-oriented system with all system components considered to be a replaceable service, allowing for incremental updates and rapid configuration.
