Query Optimization for Declarative Crowdsourcing System
Authors(2) :-Nilesh. N. Thorat, A. B. Rajmane Crowdsourcing is a distributed problem-solving, production model that has emerged in recent years. crowd sourcing is designed to hide the complexities as well as relieve the user from burden of dealing with the crowd data.. The user is requested to pass sql queries to the crowd system to generate the execution plan. Passed query is executed based on the alternative execution query plans in crowd sourcing. Here, CROWDOP a cost-based query optimization approach for declarative crowd sourcing systems is implemented. This considers both cost and latency in query optimization and provides balance between both of them. For this CrowdOp utilizes three types of queries: join queries, selection queries, and complex selection-join queries. At the end results are compared and evaluated.
