Maximal Concurrency by Locking
(1984)Proceedings of the 3rd ACM SIGACT-SIGMOD Symposium on Principles of Database Systems (PODS '84)The purpose of a database concurrency control mechanism is to control a transaction system in such a way that only serializable executions of transactions are possible; that is, safety is enforced. Locking is an appropriate means to achieve safety. In this paper the following problem is considered:Can the set of all serializable schedules (in the sense of conflict-preserving serializability) of a transaction system be defined by locking, ...Conference Paper -
