Most current approaches to concurrency control in database systems rely on locking of 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 they 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.
