Real-time system is the system where data should be processed in time. The real-time data is stored in real-time database within the specified time interval. This time interval is called as validity time interval. The validity of real-time data is maintained using different scheduling algorithms. The process of maintaining the validity of real-time data is done by using several update transactions. The appropriate scheduling algorithm is used to schedule the number of update transactions. The real-time data stored in real-time database is compared with some pre-defined value.
