Study Notes

Software Engineering Fundamentals

Software engineering is an engineering discipline that is concerned with all aspects of software production, from system specification to maintenance.
It involves using appropriate theories and methods to solve problems, considering organizational and financial constraints.

Software Engineering Importance

More and more, individuals and society rely on advanced software systems.
It is usually cheaper to use software engineering methods and techniques for software systems rather than just writing programs.

Software System Examples

Weather station system: collects weather data, carries out initial data processing, and transmits it to the data management system.
Data management and archiving system: collects data from wilderness weather stations, carries out data processing and analysis, and archives the data.
Station maintenance system: monitors the health of wilderness weather stations and provides reports of problems.

Software Functionality

Monitor instruments, power, and communication hardware and report faults to the management system.
Manage system power, ensuring batteries are charged and generators are shut down in potentially damaging weather conditions.

Application Types

Data collection systems: collect data from their environment using sensors and send it to other systems for processing.
Systems of systems: composed of multiple software systems.

Software Engineering Principles

Systems should be developed using a managed and understood development process.
Dependability and performance are important for all types of system.
Understanding and managing software specification and requirements are important.
Reuse software that has already been developed rather than writing new software.

Internet Software Engineering

The Web is now a platform for running applications, and organizations are increasingly developing web-based systems rather than local systems.
Web services allow application functionality to be accessed over the web.

Ethics and Professional Practice

Judgment: maintain integrity and independence in professional judgment.
Management: subscribe to and promote an ethical approach to software development and maintenance.
Profession: advance the integrity and reputation of the profession, consistent with the public interest.
Colleagues: be fair to and supportive of colleagues.
Self: participate in lifelong learning and promote an ethical approach to the practice of the profession.

Case Studies

A personal insulin pump: an embedded system used by diabetics to maintain blood glucose control.
A mental health case patient management system: a system used to maintain records of people receiving care for mental health problems.
A wilderness weather station: a data collection system that collects data about weather conditions in remote areas.

ACM/IEEE Code of Ethics

The code summarizes aspirations at a high level of abstraction and provides examples and details of how these aspirations change the way software engineering professionals act.
The eight principles of the code include:
- Public: act consistently with the public interest.
- Client and Employer: act in a manner that is in the best interests of the client and employer, consistent with the public interest.
- Product: ensure products and related modifications meet the highest professional standards possible.
- ... (remaining five principles)
