<p>The authors propose an integrated control mechanism and analyze the performance gain due to its use. An extension to the data sharing system structure is examined in which a shared intermediate memory is used for buffering and for early commit processing. Read-write-synchronization and write-serialization problems arise. The authors show how the integrated concurrency protocol can be used to overcome both problems. A queueing model is used to quantify the performance improvement. Although using intermediate memory as a buffering device produces a moderate performance benefit, the analysis shows that more substantial gains can be realized when this technique is combined with the use of an integrated concurrency-coherency control protocol.</p>
