MULTI-TRANSACTION CONTROL SYSTEM BY UPDATE ACCESS-COUNTER INCLUDED IN TRANSACTION-PROCESS AS STARTING POINT OF CONSISTENCY MAINTENANCE

摘要

PROBLEM TO BE SOLVED: To achieve a multi-transaction processing system which assumes real-time update having practical throughput being a requirement, in multi-transaction processing in which consistency should be maintained. SOLUTION: An update access-counter technology is applied which assumes a time when a counter is returned to an initial value depending on the up-down counting of the counter identified by a process ID of a process that is a starting point of multi-transaction processing being the completion of one multi-transaction processing, thus solving the problem.
