Hybrid Protocols Using Dynamic Adjustment of Serialization OrderReport
A real-time database system differs from a conventional database system because in addition to the consistency constraints of the database, timing constraints of individual transaction need to be satisfied. Various real~tirne transaction scheduling protocols have been proposed which employ, either a pessimistic or an optimistic approach to concurrency control. In this paper, we present new real - time transaction scheduling protocolswhich employ a hybrid approach, i.e., a combination of both pessimistic and optimistic approaches. These protocols make use of a new conflict resolution scheme called dynamic adjustment of serialization. order, which supports priority-driven scheduling, and avoids unnecessary aborts.
