Case Studies
Here we are gonna study three case studies.
An embedded system
An information system
A sensor-based data collection system
Now let us understand each of these case studies in detail.
An embedded system
This is a system where software controls and hardware devices are embedded in the device. Issues in embedded systems typically include physical size, responsiveness, power management etc. An example of an embedded system that is used is insulin pump software.
An information system
This is a system whose primary purpose is to manage and provide access to a database of information. Issues in information systems include security, usability, privacy and maintaining data integrity. An example of this information system is the hospital patient management system.
A sensor-based data collection system
This is a system whose primary purpose is to collect data from a set of sensors and process the data in some way. The key requirements of such a system are reliability, even in hostile environments, conditions and maintainability. An example of this sensor-based data collection system is the wilderness weather station.
