Study Notes
Software Engineering Fundamentals
- Software engineering involves developing software using a managed and understood development process.
- The organization developing the software should plan the development process and have clear ideas of what will be produced and when it will be completed.
Dependability and Performance
- Dependability and performance are important for all types of software systems.
- Software should behave as expected, without failures, and be available for use when it is required.
System Categories
- Embedded systems are safety-critical and require extensive verification and validation.
- Interactive web-based systems require iterative development and delivery.
- Systems of systems require detailed specifications of system interactions to be specified in advance.
Case Studies
- Wilderness weather station: collects data from a set of instruments and transmits it to the data management system.
- Digital learning environment for schools: provides a framework for a set of general-purpose and specially designed tools for learning.
Custom Software Development
- Professional software developed for a customer is not simply the programs developed and delivered.
- The most important difference between generic software product development and custom software development is that custom software is tailored to the specific needs of the customer.
Software Engineering Methods
- Using software engineering methods and techniques can be cheaper in the long run.
- These methods can help minimize the chances of having to recall cars after sale to fix software problems.
Ethical Issues
- Software engineering is concerned with ethical issues affecting the domain, such as trust, security, and social change.
- Examples of ethical issues include ensuring that software systems do not infringe on individuals' privacy or perpetuate biases.
Application Types
- Different application types require specialized software engineering techniques to support their design and development.
- Examples of application types include real-time software engineering, systems engineering, and service-oriented software engineering.
Fundamental Principles
- The fundamental software engineering principles of process, dependability, requirements management, and reuse are relevant to all types of software system.
- These principles can help ensure that software systems are developed efficiently and effectively.
Electronic Connectivity
- Electronic connectivity between various development teams can support software engineering activities.
- This can facilitate collaboration, communication, and knowledge sharing among team members.
