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.
