Optimistic concurrency control has also been applied to operations on abstract data types [Herl90].

Marx’s ‘Ultimate Aim’ in Writing , Was…e also point out how some of the previously discussed concurrency control methods can be extended to a distributed environment. In what follows we first discuss concurrency control methods for distributed databases, followed by their modeling and performance evaluation. A brief discussion of data-sharing and multidatabase systems follows.

Girjesh Govil,Ramakrishna V. Hosurlly). The wasted processing due to transaction aborts adversely affects the response time of all transactions. Thus it is important to understand how hardware resource contention affects the performance of transaction processing systems, before considering the effect of data contention.

Jerzy Neyman,Elizabeth L. Scott,[BeHG87],[GrRe92]. Only the analysis of strict two-phase locking is considered in this chapter, as is the case with almost all studies of standard locking performance (see Section 3.6 for exceptions). The lock holding time is then from the instant at which the lock is requested to transaction completion time.

The Uncertainty of Risk but the Reality of Cost, rats which developed cancerous tumors after being dosed with the toxic chemical vinyl chloride (commonly called VC) had outlived 47 dosed rats which had not developed tumors and 50 rats in a control group which were not exposed to the chemical at all. The life expectancy of rats is 104 weeks, and 9
