Abstract: Provided are a server and method for approximate query processing based on a probabilistic circuit that improve scalability and efficiency for approximate queries about operations (aggregation, statistics, and the like) mainly used in exploratory data analysis on the basis of a tractable probabilistic circuit (TPC) in a distributed network environment where various terminals (sensors, mobile computing and communication devices, and the like), network devices, and cloud infrastructures autonomously participate and continuously collect data.

Abstract: Provided are a method and apparatus for processing a data stream capable of providing a data flow processing language to support real-time processing of an exploding data stream and providing an environment for executing the data flow processing language in a cluster system. The data flow-based exploding data stream processing method includes receiving a big data real-time processing service described in a real-time data flow language, interpreting the big data real-time processing service to generate a distributed stream processing service, and distributively deploying the distributed stream processing service in a cluster system including multiple nodes and configuring an execution environment for executing the distributed stream processing service in each node.
