abstract:

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 nonlocking 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 for which these methods should be more efficient than locking are discussed.
