Study Notes

Chapter 1 - Introduction

Software engineering is a discipline concerned with all aspects of software production, from initial specification to ongoing maintenance.
Economies of developed nations are dependent on software.
Increasing reliance on software-controlled systems.
Expenditure on software is a substantial portion of GNP in developed countries.
Software costs often surpass hardware costs, especially in maintenance.
Maintaining software with a long life is often more costly than the initial development.
Software engineering methods and techniques help to build complex and demanding systems more quickly.
Failure to apply software engineering methods often results in costly and unreliable software.
Various types of software products exist, including generic (marketed to the public) and customized (developed for specific clients).
Key attributes of good software include maintainability, dependability (reliability, security, safety), efficiency, and acceptability.
Software products, by nature, require a specific set of specifications.
Fundamental principles of software engineering involve using well-managed development practices.
Software processes involved include specification, development, validation, and evolution.
Crucial factors impacting software development and/or design include heterogeneity (diverse systems), business/social changes, security and trust, scale (wide range of applicability), and software engineering diversity.
Diverse application types exist, including stand-alone, interactive transaction-based, embedded control systems, batch processing systems, entertainment systems, systems for modeling and simulation, data collection systems, and systems of systems.
Professional software engineers are bound by wider ethical responsibilities than just technical skills, encompassing integrity and independence in judgment.
Professional responsibility encompasses ethical behaviour beyond legal considerations.
Professional responsibility includes confidentiality, competence, intellectual property rights, and preventing misuse.
The ACM/IEEE Code of Ethics provides guidance for software engineers.
Several case studies are presented, illustrating various aspects of software systems (e.g. insulin pump, mental health management system, weather station, and iLearn).
Important factors in iLearn, a digital learning environment, include its service-oriented architecture, providing flexibility and allowing additions of services over time, alongside configurability, allowing for different groups of users.
