Question

What is domain in database management system examples?

Answer 1

the control action from the controller is dependent on the desired and actual process variable. In the case of the boiler analogy, this would utilise a thermostat to monitor the building temperature, and feed back a signal to ensure the controller output maintains the building temperature close to that set on the thermostat. A closed loop controller has a feedback loop which ensures the controller exerts a control action to control a process variable at the same value as the setpoint. For this reason, closed-loop controllers are also called feedback controllers.

Answer 2

In a database management system, a domain can be defined as the combination of the values which an information component may contain.

The standard for deciding the boundary of the domain might be as straightforward as an information type with a specified list of values.

For example, a domain of date of whole number is a set of all the conceivable whole numbers.
