Abstract: We study different SQL operators which are to be used in crowdsourcing system. Crowdsourcing is system which solves hard problems by combining the computer power and human logic. In crowdsourcing system, requester inputs SQL query and system processes the query, creates the execution plan and executes this plan on crowdsourcing platform. We require some SQL operators such as Select, Join, Fill, Max and Sort for the query optimization process in the crowdsourcing system. In the present paper, we studied the cited basic operations of crowdsourcing system.
