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.
