Abstract

Research on concurrency control mechanisms for database systems has had as a primary goal the discovery of techniques for allowing increased levels of concurrent execution of transactions. In this paper, we study this problem in the context of non-two-phase locking protocols which are defined for data bases in which a directed acyclic graph structure is superimposed on the data items. We introduce a new lock mode, called INV, with properties fundamentally different from locking modes previously studied and show how this allows increased concurrency. Through the introduction of the INV mode of locking we have enunciated a new principle of the theory of data base concurrency control. This principle involves the separation of the effects of the commutativity and compatibility of data manipulation operations. We then examine how the introduction of such a lock mode affects the occurrence of deadlocks in a system. Certain conditions under which deadlock-freedom is maintained are identified, and simple methods for removing deadlocks in other situations are presented,
