Abstract
In recent years research in the area of distributed transaction management has been growing rapidly. While designing concurrency control components for such systems, the most common techniques have involved locking and timestamping and variations of these. In spite of their heavy use in the designing of distributed systems, each of the above techniques has its own specific disadvantages and overhead. Our primary goal is to describe an approach that has the advantages of each of these techniques and none of their disadvantages. In this paper, we describe the Distributed Window Request Order Linked List method and show how this technique embodies most of the advantages of the standard techniques yet at the same time does not introduce serious difficulties or extra overhead of its own. We include an experimental comparison to compare transaction response time for this new method to those of locking and timpstamping methods. Keywords: distributed, database, concurrency, ROLL.
