Abstract :
Grid database is a new research area combined with the database techniques and Grid techniques, while traditional database query and optimization techniques couldn´t fully satisfy the need of Grid database because of the dynamic properties of Grid Nodes. The paper brings forward a query plan model/ NSN based on Petri net so as to describe the data relation between subquery and nodes. Based on NSN model paper further puts forward a three phases algorithm / TPs which can make dynamic optimization for subquery processing to fit for fluctuation of environment in grid , Finally the paper tests the algorithms through experiment.
