Study Notes

Software Process Activities

  • Software Specification: Involves defining requirements and constraints alongside the customer.
  • Software Development: The phase where software is designed and programmed.
  • Software Validation: Checks if the software meets customer requirements.
  • Software Evolution: Modifications made to adapt to changing customer needs and market demands.

General Issues Affecting Software

  • Heterogeneity: Software must operate across diverse systems, including mobile devices and networks.
  • Business and Social Change: Rapid technological advancements necessitate the agility to modify existing software and develop new solutions.
  • Security and Trust: Critical for software given its pervasive role in daily life.
  • Scale: Software ranges from small embedded systems to large-scale cloud services.

Software Engineering Diversity

  • Varying types of software systems require tailored techniques and tools, dependent on application type and customer requirements.

Types of Applications

  • Stand-alone Applications: Self-contained applications that run locally on a PC.
  • Interactive Transaction-based Applications: Accessed remotely, including e-commerce software.
  • Embedded Control Systems: Software managing hardware devices, predominant in numbers.
  • Batch Processing Systems: Designed for processing large heaps of data simultaneously.
  • Entertainment Systems: Primarily for personal use, aimed at user enjoyment.
  • Modeling and Simulation Systems: Used in scientific applications for simulating physical processes.
  • Data Collection Systems: Gather environmental data via sensors for processing.
  • Systems of Systems: Composed of multiple integrated software systems.

Software Engineering Fundamentals

  • Development follows a managed process tailored for specific software types.
  • Dependability and performance are essential across all systems.
  • Understanding and managing software specifications and requirements is vital.
  • Reusing pre-existing software components is preferred over developing new software.

Internet Software Engineering

  • The Web serves as a platform for application development, transitioning from local systems to web-based applications.
  • Web Services: Enable functionality access online.
  • Cloud Computing: Offers remote application services where users pay based on usage.

Web Software Engineering

  • Software Reuse: A vital strategy for constructing web-based systems by utilizing existing components.
  • Incremental and Agile Development: Encourages developing systems in stages; comprehensive requirements are often impractical upfront.

Software Engineering Ethics

  • Engineers bear wide responsibilities beyond technical skills.
  • Ethical conduct is necessary for respect within the profession.
  • Ethical behavior encompasses moral principles alongside legal compliance.

Issues of Professional Responsibility

  • Confidentiality: Respecting employer or client confidentiality is critical.
  • Competence: Engineers should accurately represent their capabilities and refrain from overstepping their expertise.
  • Intellectual Property Rights: Protecting the rights of employers and clients is essential, with awareness of relevant laws.
  • Computer Misuse: Ethical responsibilities include refraining from unethical computer use, which can range from minor infractions to serious breaches.

ACM/IEEE Code of Ethics

  • A collaborative framework from professional societies offering ethical guidelines for software engineers.
  • Eight fundamental principles govern professional behavior in software engineering.

Rationale for the Code of Ethics

  • Software engineers' influential roles in various sectors necessitate a commitment to ethical practices.
  • Their impact can either promote or undermine societal benefits, underscoring the importance of ethical commitment.

Ethical Principles

  • Public: Act in alignment with public interest.
  • Client and Employer: Prioritize the interests of clients while maintaining public interest.
  • Product: Uphold high professional standards for products.
  • Judgment: Independently maintain integrity in decision-making.
  • Management: Promote ethical management in software development.
  • Profession: Enhance the integrity of the profession.
  • Colleagues: Support and treat colleagues fairly.
  • Self: Engage in continuous learning and promote ethical practices.

Ethical Dilemmas

  • Potential conflicts include disagreement with senior management policies.
  • Ethical concerns when releasing untested safety-critical systems.
  • Participation in ethically contentious projects like military weaponry development.
