An embodiment of the invention may include a method, computer program product and computer system for managing mobile objects. The embodiment may determine, by a mobile object server, a position of a mobile object in a geographic space managed by the mobile object server. The embodiment may determine a plurality of routes based on the position of the mobile object in the geographic space. The embodiment may calculate, by the mobile object server, a plurality of route parameters for the plurality of routes, wherein the plurality of route parameters includes a passage possibility of the mobile object over each route. The embodiment may calculate a plurality of edge parameters for a plurality of edges, wherein each edge is a segment of a route, and wherein the edge parameter includes the passage possibility of the mobile object over each edge.

Management of mobile objects

An aggregation processing system includes a data transmission unit for transforming data which is a target of an aggregation process into a format of a tuple having a key and for transmitting the tuple to a data processing unit, and the data processing unit for performing an aggregation process of a tuple which has been transmitted. When a tuple transmitted from the data transmission unit is received, the data processing unit invokes an operator and performs an aggregation process. In the aggregation process, aggregated data is generated based on the tuple received by the data processing unit and a related input table, and writing to an output table or generation of an output tuple is performed based on the generated aggregated data. A plurality of aggregation processes are implemented by combining processes by the operators, and the plurality of aggregation processes are performed as one transaction.
