Study Notes
Software Attributes
- Good software delivers the required functionality and performance to the user.
- Maintainability, dependability, and usability are essential software attributes.
Software Engineering
- Software engineering is an engineering discipline concerned with all aspects of software production.
- There are fundamental software engineering activities: software specification, software development, software validation, and software evolution.
Software Engineering vs. Computer Science
- Computer science focuses on theory and fundamentals.
- Software engineering is concerned with the practicalities of developing and delivering useful software.
Software Engineering Challenges
- Challenges include coping with increasing software diversity, demands for reduced delivery times, and the need to develop trustworthy software.
Software Engineering Costs
- Roughly 60% of software costs are development costs, while 40% are testing costs.
- For custom software, evolution costs often exceed development costs.
Software Engineering Techniques and Methods
- Projects should be professionally managed and developed.
- Different techniques are appropriate for different types of systems.
- Game development often uses prototyping, while safety critical control systems require complete and analyzable specifications.
Professional Responsibility
- Engineers should respect the confidentiality of their employers or clients, even when a formal confidentiality agreement is not signed.
- Engineers with appropriate experience should not misrepresent their level of professional competence.
- Engineers should not accept work that is outside of their competence.
Intellectual Property Rights
- Engineers should understand local laws governing the use of intellectual property, including patents and copyrights.
- Protecting the intellectual property of employers and clients is essential.
Computer Misuse
- Software engineers should not misuse their professional skills to access another person’s computer.
- Misuse ranges from relatively trivial, such as game playing on an employer's machine, to extremely serious, such as the dissemination of viruses.
ACM/IEEE Code of Ethics
- Professional societies in the United States have created a code of ethical practice.
- Members of these organizations sign up to the code of practice when they join.
- The Code contains eight principles that guide the behavior and decisions of professional software engineers.
Ethical Principles
- Public: Software engineers should act in a way that is consistent with the public interest.
- Client and Employer: Software engineers should act in the best interests of their client and employer, always considering the public interest.
- Product: Software engineers should ensure that their products and modifications meet the highest professional standards.
- Judgment: Software engineers must maintain integrity and independence in their professional judgment.
- Management: Managers and leaders in software engineering should subscribe to and promote an ethical approach to the management of software development and maintenance.
Mentcare System Organization
- The Mentcare system is organized as a system to manage the care and treatment of patients.
Key Features of the Mentcare System
- Provides individual care management, allowing clinicians to create patient records, edit information, view patient history, and access data summaries.
- Includes patient monitoring capabilities to alert medical staff of potential problems.
- Generates administrative reports for management purposes, including statistics on patient numbers, treatments, and drug usage.
Mentcare System Concerns
- Privacy: Patient information must be kept confidential and only accessible by authorized medical staff and the patient themselves.
- Safety: The system should warn medical staff about potentially suicidal or dangerous patients.
- Availability: The system must be available when needed to ensure that safety is not compromised and patients can receive appropriate medication.
Wilderness Weather Station
- The government of a country with large wilderness areas deployed several hundred weather stations in remote areas.
- Stations collect data from instruments that measure various climate parameters like temperature, pressure, sunshine, rainfall, wind speed, and direction.
Weather Station Environment
- Weather stations are often located in harsh and remote environments where weather elements can impact their operation.
Weather Information System
- The weather station system is responsible for collecting weather data, carrying out initial data processing, and transmitting it to the data management system.
- The data management and archiving system collects data from all wilderness weather stations, processes and analyzes it, and archives the data.
- The station maintenance system communicates with wilderness weather stations to monitor their health and report any problems.
Additional Weather Station Software Functionality
- Monitor the instruments, power and communication hardware, and report faults to the management system.
- Manage the system power, ensuring batteries are charged when possible but generators are shut down in potentially damaging weather conditions.
- Support dynamic reconfiguration, where parts of the software are replaced, and backup instruments are switched in during failure.
iLearn: A Digital Learning Environment
- A digital learning environment provides tools for learning, including general-purpose applications, learning management applications like a Virtual Learning Environment (VLE), games, and simulations.
iLearn: Service-Oriented Systems
- The system is a service-oriented system with all components considered replaceable services.
- This allows incremental updates and rapid configuration for different groups, such as young children or senior students.
iLearn Services
- Utility services offer application-independent functionality that can be used by other services.
- Application services provide specific functions like email, conferencing, photo sharing, and access to educational content.
- Configuration services allow the environment to be adapted with specific sets of application services and define service sharing.
iLearn Architecture
- The iLearn architecture involves a set of interconnected services that work together to create a comprehensive learning environment.
iLearn Service Integration
- Integrated services provide an API (application programming interface) allowing communication and information sharing between other services.
- Independent services are accessed through a browser interface and operate independently of other services.
- Sharing information between independent services requires user action like copy and paste, and re-authentication may be needed.
Key Points to Remember
- Software engineering is an engineering discipline focused on all aspects of software production.
- Maintainability, dependability, security, efficiency, and acceptability are crucial software product attributes.
- The high-level activities of specification, development, validation, and evolution are part of all software processes.
- The fundamental notions of software engineering are applicable to various system development types.
