Study Notes

Application Types

Interactive transaction-based applications are accessed by users from their PCs or terminals and execute on a remote computer, including web applications like e-commerce platforms.
Embedded control systems control and manage hardware devices and are likely the most numerous type of system.
Batch processing systems process large quantities of data in batches to generate outputs.
Entertainment systems are for personal use and provide entertainment to the user.
Systems for modelling and simulation are designed by scientists and engineers to simulate physical processes or situations.
Data collection systems collect data from their environment using sensors and send it to other systems for processing.
Systems of systems are composed of multiple other software systems.

Software Engineering Fundamentals

A managed, understood development process is crucial for all software systems, although different processes are used for different systems.
Dependability and performance are also critical for all types of software systems.
Understanding and managing software specifications and requirements is important.
Where appropriate, reusing already developed software is preferable to writing new software.

Software Engineering and the Web

Organizations are increasingly developing web-based systems rather than local systems.
Web services allow application functionality to be accessed over the web.
Software engineers must behave ethically and honestly to be respected as professionals.

Issues of Professional Responsibility

Confidentiality requires engineers to respect the confidentiality of their employers or clients.
Competence implies that engineers should not misrepresent their skills and should not accept work outside their capabilities.
Intellectual property rights require engineers to be aware of local laws and to protect the intellectual property of their employers and clients.
Computer misuse, which ranges from game playing on an employer's machine to spreading viruses, should be avoided by software engineers.

ACM/IEEE Code of Ethics

The ACM and IEEE have jointly created a code of ethical practice for software engineers.
Members of these organizations are expected to follow the code of practice.
The code outlines eight principles related to the behavior of software engineers, including practitioners, educators, managers, and students.

Rationale for the Code of Ethics

Computers play a vital role in society, and software engineers contribute to their design, development, and maintenance.
Software engineers have the opportunity to use their skills for good or harm.
To ensure the ethical use of software, engineers need to commit to making it a beneficial and respected profession.

Ethical Principles

Public: Software engineers should act in the best interests of the public.
Client and Employer: Engineers should act in the best interests of their clients and employers, consistent with the public interest.
Product: Engineers should ensure that their products meet the highest professional standards.
Judgment: Engineers should maintain integrity and independence in their professional judgment.
Management: Software engineering managers should promote an ethical approach to software development and maintenance.
Profession: Engineers should advance the integrity and reputation of the profession.
Colleagues: Engineers should be fair and supportive of colleagues.
Self: Engineers should participate in lifelong learning to maintain their professional expertise and ethics.

Ethical Dilemmas

Disagreement with management policies.
Employer's unethical behavior such as releasing a safety-critical system without proper testing.
Participation in the development of military or nuclear weapons systems.

Case Studies

Insulin Pump: An embedded system that controls insulin delivery for diabetics.
Mental Health Case Patient Management System: A system for managing patient records and treatments in mental health care.
Wilderness Weather Station: A data collection system for gathering weather data in remote areas.

Insulin Pump Control System

Collects data from a blood sugar sensor and calculates the required insulin dose.
Calculations are based on the rate of change of blood sugar levels.
The system sends signals to a micro-pump to deliver the correct insulin dose.
This is a safety-critical system, as incorrect insulin doses can lead to dangerous health consequences.

Insulin Pump Hardware Architecture

Features a micro-controller, a blood glucose sensor, a micro-pump, and a display screen.

Activity Model of the Insulin Pump

Demonstrates the activities involved in the functioning of the insulin pump, including sensor data collection, blood sugar analysis, insulin dose calculation, and insulin delivery.

Essential High-Level Requirements

The system must be available to deliver insulin when needed.
The system must deliver the correct amount of insulin reliably.

A Patient Information System for Mental Health Care

A medical information system for managing records of patients suffering from mental health problems and their treatments.
The system supports patient care at clinics and helps manage clinical operations.
The system can be accessed from various locations, even those with limited network connectivity.

MHC-PMS (Mental Health Care - Patient Management System)

Designed to provide comprehensive patient information management and reporting for mental health clinics.
The system can operate both online and with downloaded data, supporting multiple clinic locations.

MHC-PMS Goals

Generate management information for performance assessment against local and government targets.
Provide medical staff with timely information for patient treatment.

The Organization of the MHC-PMS

Features a central database, local copies for individual clinics, and various modules for patient management, patient monitoring, and administrative reporting.

MHC-PMS Key Features

Individual Care Management: Supports patient record creation, information editing, history viewing, and data summaries for quick reference.
Patient Monitoring: Continuously monitors patient records and alerts medical staff to potential problems.
Administrative Reporting: Generates monthly management reports about patient numbers, treatments, medication prescriptions, and other key metrics.

MHC-PMS Concerns

Privacy: Ensures patient information confidentiality.
Safety: Warns medical staff about potentially suicidal or dangerous patients.
Availability: Ensures the system is available for critical patient care and medication prescriptions.
