Study Notes

Introduction to Software Engineering

Software engineering is crucial for the functioning of government, society, and national and international businesses and institutions.
Software is essential for national infrastructures and utilities, industrial manufacturing and distribution, the financial system, and entertainment.

Characteristics of Software Systems

Software systems are abstract and intangible, not constrained by physical laws or manufacturing processes.
This allows for great flexibility, but also makes software systems prone to complexity and expensive to change.

Types of Software Systems

Embedded systems (e.g., in portable or wearable devices)
Data collection and analysis systems (e.g., collecting data from sensors and sending it for processing)
Systems of systems (e.g., enterprise resource planning systems composed of multiple software systems)
Batch processing systems (e.g., used in conjunction with web-based transaction systems)

Challenges in Software Engineering

The need for fast delivery of new software systems and rapid changes to existing ones.
Ensuring security and trust in software systems, especially for remote systems accessed through the web.
Developing software across a wide range of scales, from small embedded systems to large, cloud-based systems.

Software Engineering Diversity

Software engineering involves a systematic approach, considering practical costs, schedules, and dependability issues, as well as customer and producer needs.

Ethics in Software Engineering

Professional societies and institutions, such as the ACM and IEEE, publish codes of ethics and professional conduct for software engineers.
These codes establish standards for ethical behavior, including fairness, integrity, and lifelong learning.
Software engineers have responsibilities to the engineering profession and society, beyond just technical issues.
