Our project proposes a general framework of an aglet based approach for constraint checking and Query processing across multiple databases. Our architecture is completely distributed, where in we have a constraint checker module running on each database. We have presented the design of the constraint checker module and the data updater module. The constraint checker module has the ability to check if a given update statement violates any global constraints and the data updater module updates the global database. Our main contribution is the design of a faster and speedy constraint checking mechanism. The reason is sub constraint checks on remote databases are executed in parallel by mobile agents.
