Performance of Concurrency Control Mechanisms in Centralised Database Systems
This paper is to propose user control system that definitely increases the performance of real-time data service. However the most existing work on this RTDB was based on very critical closed loop control system. To overcome this problem, they design a system called user control database model which stimulate the overload transaction during run time. They also design quality of service scheme and it allows to setting requirements for QOS transaction. The performance of proposed algorithm evaluated in different experiments. So the proposed system will definitely satisfies their needs even critical conditions like overload or run-time errors.
