Big data system

The invention provides a big data system. The system comprises a big data foundation platform, a sharing resource base, a visualized editing and displaying subsystem and a flow dispatching subsystem. The system combines various existing big data processing systems; a specific big data processing system is submitted based on a data processing flow dispatching program resource generated by user edition and a data resource and is used for carrying out data processing, so that the utilization threshold of the big data system is greatly reduced, big data related sources in organizations can be conveniently shared and a data processing flow can be reused and can be taken over.
