Study Notes

Software Engineering Overview

  • Software engineering concerns all aspects of software production.
  • Software engineering activities include specification, development, validation, and evolution.
  • Software engineering is concerned with the practical aspects of delivering useful software.
  • 60% of software costs are development, and 40% are testing.

Ethical Responsibilities in Software Engineering

  • Software engineers should protect the intellectual property of their employers and clients.
  • Software engineers should avoid computer misuse which can range from trivial (game playing on an employer’s machine) to serious (dissemination of viruses).
  • The ACM/IEEE Code of Ethics provides eight principles for software engineers:
    • Public
    • Client and Employer
    • Product
    • Judgment
    • Management
    • Profession
    • Colleagues
    • Self

Ethical Dilemmas

  • Ethical dilemmas include disagreeing with senior management's policies, employers acting unethically, participating in the development of military or nuclear systems.

Case Studies

  • Insulin Pump Control System:
    • Embedded system that collects blood sugar data and calculates insulin dosage.
    • Critical safety system as low or high blood sugar levels have serious health consequences.
  • Mentcare (Mental Health Case Patient Management System):
    • Maintains patient records and supports mental health care.
    • Importance of system availability for patient safety.
  • Wilderness Weather Station:
    • Collects weather data from remote locations.
    • Includes instruments for temperature, pressure, rainfall, wind speed, and direction.
  • iLearn:
    • Digital learning environment to support education in schools.

Essential High-Level Requirements

  • The system shall be available to deliver insulin when required.
  • The system shall perform reliably and deliver the correct insulin dosage.
  • The system shall be designed and implemented to ensure it meets all requirements.

Weather Information System

  • Three components:
    • Weather station system: collects and processes data, transmitting it to the data management system.
    • Data management and archiving system: collects data from all stations, processes, analyzes, and archives data.
    • Station maintenance system: communicates with stations to monitor their health and report problems.

Additional Software Functionality for Weather Station

  • Monitor instruments, power, and communication hardware.
  • Manage the system power, ensuring batteries are charged and generators are shut down in damaging weather.
  • Support dynamic reconfiguration, allowing for software updates and backup instrument switching.
