A Three-stage Model of Incremental Maintenance of Multi-materialized Views

WANG Teng-jiao; WANG Hai-yang; HONG Xiao-guang; DONG Ji-run(DePartment of Computer Science and Technology Beljing University Beijing 100871 )(Department of COmputer Science Shandong University Ji'nan 250100)  
A new method is presented in this paper, which is about incremental maintenance of multi-materialized views based on parallel pipeline process. In this process, the authors classify all the materializedviews first by using choosing methods, then by classified topological sorting, so that no nested definitions ofrelations exist among these views. Finally, in order to maintain the incremental multi-materialized views, theyprocess in parallel all the views by utilizing pipeline model of semaphore process mechanism.
