On Optimistic Methods for Concurrency Control.

Abstract

Most current approaches to concurrency control in database systems rely on locking of a data objects as a control mechanism. In this paper, two families of non-locking concurrency controls are presented. The methods used are ('optimistic' in the sense that rely mainly on transaction backup as a control mechanism, 'hoping' that conflicts between transactions will not occur. Applications where these methods should be more efficient than locking are discussed. (Author)
