Research on concurrency control in office automation system

At present, the concurrency control strategy in office automation system has limitations, which easily make the modified contents overwritten or fail to flow the document in the specified order, etc. In order to solve the problems, the pessimistic and optimistic concurrency control strategies are separately studied and analyzed in detail in this paper. The technologies of “heartbeat” and database trigger are presented to improve concurrency control mechanism. Practical application in office automation system shows that the results are satisfactory.
