Query Methodology for Advanced Structured Using Crowd sourcing Systems

Abstract

Query optimization is an important aspect in crowdsourcing system. We consider the optimized crowdsourcing system uses SQL operators based crowdsourcesystem. The client is required to gift a SQL-like operator and framework assumes the liability of process  in the inquiry making the execution stating and upload withthe crowd sourcingoriginations. The relational databasemodel , Query mythology is providing query structured is important for crowdsourcing. The propose system, a cost-based query optimization approach for crowdsourcing systems. The cost and time is consider in query optimization objective is proposed methods and generates query plans that give a good balance between the cost and latency.A main change in latest closed-world model for query processing is not hold for human input. From an implementation perspective, human-oriented query operators in solicit, integrate and cleanse crowdsourced data. The system develops efficient algorithms uses optimizing selection queries, join queries, and complex selection-join queries using parallel system. WSe are analyzing the various approaches that help to resolve the user queries in crowd sourcing modelis supports cost based query optimization, optimizing multiple crowd sourcing operators and access tradeoff in between cost from monetary point of view and latency.
