Study Notes
Frequently Asked Questions about Software Engineering
- Key challenges include increasing diversity, demand for reduced delivery times, and the need for trustworthy software.
- Software costs are approximately 60% for development and 40% for testing; in custom software, evolution costs can surpass development costs.
- Effective software engineering techniques vary based on the system type, such as prototyping for games and comprehensive specifications for safety-critical systems.
- The web has revolutionized software engineering by increasing the availability of software services and enabling the development of highly distributed systems.
Software Products
- Generic products are stand-alone systems marketed to any customer.
- Interactive transaction-based applications run remotely and are accessed through user PCs, exemplified by e-commerce platforms.
- Embedded control systems govern hardware devices, with a greater quantity of these systems in existence compared to other types.
Application Types
- Batch processing systems handle large volumes of data inputs to generate outputs efficiently.
- Entertainment systems are designed for personal use and focus on user entertainment.
- Modeling and simulation systems help scientists and engineers replicate physical processes involving multiple interacting objects.
- Data collection systems gather environmental data using sensors for further processing.
- Systems of systems comprise multiple software systems integrated into a larger framework.
Software Engineering Fundamentals
- Fundamental principles, like using a managed development process, apply across all software types, albeit with varied processes suited to different software.
- Dependability and performance are crucial for all systems.
Web Software Engineering
- Service-oriented systems utilize stand-alone web services for software implementation.
- Rich interfaces are enhanced by technologies like AJAX and HTML5, enabling advanced web browser capabilities.
Software Engineering Ethics
- Involves responsibilities beyond technical skills; ethical behavior is essential for professional respect.
- Ethical standards involve adherence to moral principles alongside legal requirements.
Issues of Professional Responsibility
- Confidentiality should always be respected regarding employers and clients, with or without formal agreements.
- Engineers must accurately represent their competence and avoid taking on work beyond their capabilities.
- Awareness of intellectual property laws is critical to protect employers’ and clients' copyrights and patents.
- Engineers must refrain from misusing others' computers, which can range from minor infractions to serious offenses.
ACM/IEEE Code of Ethics
- Developed by professional societies in the US, detailing ethical practice for software engineers.
- Members commit to eight principles guiding their professional behavior, applicable to practitioners, educators, and policy makers.
Rationale for the Code of Ethics
- Software plays a pivotal role across various sectors (commerce, government, etc.), instilling a responsibility for software engineers in design, development, and testing.
- Engineers have the opportunity to impact society positively or negatively, necessitating a commitment to ethical practices in software engineering.
Wilderness Weather Station
- To enhance weather monitoring in remote areas, several hundred weather stations will be implemented.
- Stations collect and measure data like temperature, pressure, and wind characteristics through embedded software systems.
- Each instrument periodically records data and manages information collection.
Weather Information System
- The weather station system processes and transmits collected weather data.
- The data management system archives data collected from all stations, facilitating analysis and storage.
- The maintenance system monitors the health of the weather stations through satellite communication, reporting any issues.
Additional Software Functionality
- Systems will also include the capability to monitor instruments and report any faults related to power and communication hardware.
