Study Notes
Software Engineering Introduction
- Software engineering is a field focused on theories, methods, and tools for professional software development.
- All developed nations rely heavily on software.
- Software costs often exceed hardware costs, and maintenance costs are frequently multiples of development costs.
- Software engineering prioritizes cost-effective development.
Topics Covered
- Software and Software Engineering
- Software Engineering Ethics
Software Project Failure
- Increasing system complexity makes demands for larger and more complex software systems, which can be challenging and even impossible.
- Many companies skip software engineering for quicker development, causing higher costs and lower reliability.
Software Products
- Generic products are marketed to multiple customers, examples include general PC software.
- Customized products are tailored to meet a specific customer's needs, examples include embedded control systems such as air traffic control.
Product Specification
- For generic products, the software developer defines the specification and makes changes.
- For customized products, the customer defines the specification and makes decisions about changes.
Essential Attributes of Good Software
- Maintainability: The software must be able to adapt to changing customer needs.
- Dependability and Security: The software must be reliable, with no damage to users or systems.
- Efficiency: Software should not use excessive resources like memory and processing power.
- Acceptability: The software must be user-friendly and compatible with other systems.
Software Engineering
- Software engineering is a discipline concerned with all aspects of software production, from initial design to ongoing maintenance.
- It relies on appropriate theories and methods to solve problems, considering organizational and financial constraints.
- It's not just development; it also includes project management and tools development to support the overall process.
Importance of Software Engineering
- Individuals and society rely heavily on advanced software systems, demanding reliable and economical software creation.
- Software engineering methodologies are generally more cost-effective for system development in the long run than ad-hoc methods.
Software Process Activities
- Software Specification: Customers and engineers define the software and its operational constraints.
- Software Development: The software is designed and programmed.
- Software Validation: The software is checked and verified to meet customer requirements.
- Software Evolution: Software is modified to reflect changing customer and market needs.
General Issues Affecting Software
- Heterogeneity: Systems are often distributed across different networks and devices (computers, mobiles).
- Business and Social Change: Business and society change quickly, requiring the ability to modify and develop new software.
- Security and Trust: Software must be reliable and trusted to ensure safety.
- Scale: Software must operate across a range of sizes from simple to global systems.
Software Engineering Diversity
- Different types of software systems exist. There's no universal method for all software.
- The best approaches depend on application type, customer needs, and development team expertise.
Application Types
- Stand-alone: Runs on a local computer.
- Interactive Transaction-Based: Runs on a remote computer, accessed by PCs and terminals (e.g., e-commerce).
- Embedded Control: Controls hardware (e.g., air traffic control).
- Batch Processing: Processes large batches of data.
- Entertainment: Designed for personal entertainment.
- Modeling and Simulation: Used for modeling and testing physical processes.
- Data Collection Systems: Collect data using sensors.
- Systems of Systems: Sophisticated systems combining numerous components.
Software Engineering Fundamentals
- Principles apply to all software systems, regardless of the development method.
- Developing processes should be managed and understood.
- Dependability and performance are essential.
- Software specification and requirements must be understood and well-managed.
Internet Software Engineering
- The Web is the most used software platform.
- Web-based development is a major focus.
- Web Services allow access over the web.
- Cloud is a method for providing remote computer and application services.
Web-based Software Engineering
- Web systems are complex but still follow the same fundamental principles as other software systems.
- Fundamental software engineering ideas are applied to web-based software similarly to other applications.
Web Software Engineering
- Software reuse is the dominant approach for web development.
- Incremental and agile development models are common.
- Service-oriented systems, AJAX, and HTML5 technologies are used to support richer web interfaces.
Software Engineering Ethics
- Software engineering has wider responsibilities than just technical skills.
- Engineers must act honestly and ethically.
- Ethical behavior goes beyond following laws and includes moral principles.
Issues of Professional Responsibility
- Confidentiality: Respecting the confidentiality of clients and employers.
- Competence: Not misrepresenting skills and accepting projects beyond one's ability.
- Intellectual Property: Respecting copyright and patent laws to maintain data security.
- Computer Misuse: Not using skills to misuse others' computers.
ACM/IEEE Code of Ethics
- Professional societies in the US have a code of ethics.
- Members agree to follow the code after joining.
- The code has principles for software engineers at various stages and roles within the profession.
Rationale for the Code of Ethics
- Software engineers impact numerous parts of society and have opportunities to do good or cause harm.
- Engineers should commit to making software engineering a positive and respected profession.
ACM/IEEE Code of Ethics
- Aspiration and detail are part of the code; they need to be considered together
- Software engineers are responsible for making software systems a benefit to society, and to protect intellectual property and be well-behaved
Ethical Principles
- Public Interest: Act consistently in the public's benefit.
- Client and Employer: Act in client and employer best interest.
- Product: Develop high-quality products.
- Professional Judgment: Make sound, unbiased judgments.
- Management: Manage software development ethically and effectively.
- Profession: Advance professionalism within the field.
- Colleagues: Support and be fair to co-workers.
- Self: Continuously improve skills and encourage ethics throughout the profession.
Ethical Dilemmas
- Disagreements with management policies.
- Unethical employer actions, such as releasing untested software.
- Participating in the development of controversial systems like military weapons or nuclear systems.
