Optimizing the incremental maintenance of multiple join views Ki Yong Lee and Myoung-Ho Kim   View Paper (PDF)   Return to Query Processing and View Maintenance Abstract , we proposed the delta propagation strategy that computes the change of a join view in a recursive manner. We extend the delta propagation strategy to multiple views. The recursive property of the strategy makes it possible to share common intermediate results among views effectively. We first define the multiple view maintenance problem, then a heuristic algorithm that finds a global maintenance plan for the given views is proposed. We also present experimental result that shows the efficiency of the proposed method. ©2006 Association for Computing Machinery
