Study Notes
Types of Systems
- Examples of batch systems include periodic billing systems and salary payment systems.
- Entertainment systems are primarily for personal use and intended to entertain the user, with quality of user interaction being the most important characteristic.
- Systems for modeling and simulation are developed by scientists and engineers to model physical processes or situations, and are often computationally intensive.
- Data collection systems collect data from their environment using sensors and send it to other systems for processing.
Software Engineering Techniques
- Different software engineering techniques are used for different types of systems.
- For example, an embedded control system in an automobile is safety-critical and requires extensive verification and validation.
- There are no universal software engineering methods and techniques that are suitable for all systems and all companies.
- The type of application being developed is the most significant factor in determining which software engineering methods and techniques are most important.
Types of Applications
- Stand-alone applications run on a local computer, such as a PC, and include all necessary functionality.
- Interactive transaction-based applications execute on a remote computer and are accessed by users from their own PCs or terminals.
- Embedded control systems control and manage hardware devices.
- Batch processing systems are business systems that process data in large batches and have minimal user interaction.
Software Engineering Ethics
- Software engineering involves wider responsibilities than simply the application of technical skills.
- Software engineers must behave in an honest and ethically responsible way to be respected as professionals.
- Ethical behavior is more than simply upholding the law.
- Issues of professional responsibility include confidentiality, competence, intellectual property rights, and computer misuse.
