To improve resource utilization efficiency of query compliance check, which is check as to whether a query complies with a restriction imposed on data. The query compliance check is roughly divided into data flow policy check as to whether a data flow policy that defines a restriction on data transfer within a county or between countries is complied with, and organization rule check as to whether an organization rule that defines a restriction on sharing outside an organization is complied with, which are hierarchically configured. By analyzing a received query, a system identifies one or more data items as target input/output (I/O) data according to the query, and executes the data flow policy check on the identified one or more data items. When a result of the data flow policy check is false, the system returns a result that the query is compliance violation without executing the organization rule check.

Query processing system and method

Example implementations described herein estimate parameters for equipment that cannot be sensed directly, including determining if such equipment is running or stopping. Example implementations determine the standard throughput per equipment and product, based on history of equipment production data, extract previous and next equipment of robotic arms on the line by using physical topology information of robot arms and equipment, senses and determines throughput of associated robot arms and compares the robot arm throughput with the standard throughputs of the previous and next equipment, which help determine whether the previous/next equipment have stopped.

Equipment status estimation method and system

Provided is an information processing apparatus performing: storing traceability information that is information which results from associating an apparatus that processes the component, an operating person who is in charge of the processing, and a timing at which the processing is performed, with each other; storing processing situation information that is information that results from associating a situation of the processing of the component and a timing at which the processing is performed, with each other; generating a combination at the same timing, of the processing, the apparatus or the operating person, and the situation of the processing, as an object integration data, based on the traceability information and the processing situation information; and outputting contents of the generated object integration data.

Manufacturing management method and manufacturing management system

Example implementations described herein are directed to systems and methods for non-invasive data extraction from digital displays. In an example implementation, a method includes receiving one or more video frames from a video capture device capturing an external display, where the external display is independent the video capture device; determining one or more locations within the external display comprising time varying data of the external display; and for each identified location of the time varying data: determining a data type; applying one or more rules based on the data type; and determining an accuracy of the time varying data within the one or more frames based on the rules.

Non-invasive data extraction from digital displays

A computer system, comprising a plurality of computers; and a management computer, wherein a plurality of data stores which store data obtained from a data source and having differing attributes, wherein the management computer has a request allocation unit and holds metadata management information. The request allocation unit is configured to: refer to the metadata management information to select a candidate data store based on analysis results of the data obtaining request including the time attribute of the requested data; determine whether the requested data can be obtained from the candidate data store; determine a data store to which to issue a request for obtaining the requested data; and issue the request to the determined data store.

Computer system

There is provided a work data management system which includes a detailed step classification unit that classifies work performed by a worker at a work site into a plurality of time-series detailed steps based on work data including image data of the work site and a data visualization unit that causes a result display unit to display at least the image data and the plurality of time-series detailed steps.

Work data management system and work data management method

A data processing apparatus generates by a stream processing control program, for a time-series first stream data group of stream data out of a time-series stream data sequence, first vector data including elements acquired by collecting respective pieces of stream data of the time-series first stream data group; generates, by the stream processing control program, for a time-series second stream data group including, as a head, a piece of intermediate stream data of the time-series first stream data group and having the same number of pieces of data as the time-series first stream data group, second vector data including elements acquired by collecting respective pieces of stream data of the time-series second stream data group; and inputs, by the stream processing control program, the first and second vector data generated respectively to a batch program to control the batch program to carry out a batch processing.

Data processing apparatus and data processing method

A user specifies a group by a user-defined query. An input order is assured among data of a same group. By outputting data belonging to a same group from the same node, an order inputted for a necessary portion is assured. By outputting data belonging to different groups from another node, processing in plural nodes is achieved to avoid reduction in performance.
