These protocols as well ensure that the system will never enter a deadlock state although the way it is done is different from deadlock prevention. In this way whenever a transaction requests for some data, the system refer the resources currently allocated to each procedure and the future requests and releases of each process currently allocated to each procedures and the future requests and releases of every process, to decide whether the current request can be satisfied or should wait to prevent a possible future deadlock. In this the transactions must give additional information about how in future the data will be requested.
