Parallel Execution of Transaction and Integrity Rules for Maintaining Database Integrity

摘要

An important aim of a database system is to guarantee database consistency, which means that the data contained in a database is both accurate and valid. Integrity constraints represent knowledge about data with which a database must be consistent. The process of checking constraints to ensure that update operations or transactions which alter the database will preserve its consistency has proved to be extremely difficult to implement. In this paper, we proposed techniques to be performed at run-time which will effectively reduce the cost of maintaining database integrity by exploring the possibility of executing the transaction and enforcing the integrity rules in parallel.
