Abstract: To determine a communication scheme capable of causing an API to be efficiently executed in accordance with a processing content of the API. An API management system includes an API processing time estimation unit that acquires information of an execution request of an API, estimates a required time required for a predetermined information processing apparatus to execute the API in response to the information of the execution request of the API by analyzing a processing content of the API indicated by the execution request of the API, and determines a communication scheme used for transmitting a request for causing the predetermined information processing apparatus to execute the API to be either synchronous communication or asynchronous communication based on the estimated time.

Abstract: Software that implements processing executed through coordination between multiple hubs is efficiently developed. An information processing system comprises a plurality of AP execution devices that are information processing apparatuses provided in each of a plurality of hubs to execute AP software. Each of the AP execution devices stores common AP software that executes the same processing blocks in the same order. The AP software includes transfer processing blocks implementing processing to coordinate processing of the processing blocks executed by a first one of the AP execution devices in a first one of the hubs with a second one of the AP execution devices in a second one of the hubs. Once the processing reaches a first one of the transfer processing blocks during sequential execution of the processing blocks of the AP software, the first AP execution device transmits a coordination start message notifying of start of the coordination, to the second AP execution device. Once the second AP execution device receives the coordination start message, the second AP execution device starts sequential execution from a processing block following the first transfer processing block.

Abstract: A computer system that processes data among a plurality of sites each including a computer having a processor and a memory. The computer includes an application for performing predetermined processing on data, an execution manager for managing execution of the application, and data transfer policies specifying whether data of a processing result of the application is allowed to be transmitted to the external. The execution manager generates information on data used by the application being executed as information on data to be transmitted and applies the data transfer policies to the data in the information on data to be transmitted to determine whether the data to be transmitted can be transmitted to the outside of the site.

Abstract: A data flow containing a distributed processing starting block, a distributed processing ending block, and a distributed processing target block which is a block described between the distributed processing starting block and the distributed processing ending block is edited by using a flow editor. A master apparatus forming a cluster transmits a message containing an execution instruction of the distributed processing target block to worker apparatuses forming the cluster when the distributed processing starting block has been reached at the time executing the data flow, and upon receipt of the message, each of the worker apparatuses executes the distributed processing target block and transmits a message containing an execution result of the distributed processing target block to the master apparatus, and upon receipt of the execution results from the worker apparatuses, the master apparatus executes a block of the data flow which follows the distributed processing ending block.

Abstract: The design and development of a data analysis process is assisted and the burden on the user such as a data analyst in data analysis process is reduced. For a data analysis performed by executing each of a data access process, a data analysis process, and an analysis result visualization process, a data analysis process assistance device stores analysis process setting information including setting information for variables commonly used between the respective processes, and plugins corresponding to the respective processes, each of the plugins including basic information that is information on contents of the respective processes, a program code used as a base to generate a template for a program for achieving each of the processes, the variables of the analysis process setting information, and a description related to a variable cross-referenced between the respective processes; and generates the template while ensuring a relationship or consistency between the analysis process setting information and the plugins corresponding to the respective processes.

Abstract: A distributed data processing system configured to perform distributed processing of multiple data processing processes at multiple processors includes: a data storage configured to store data to be processed through the data processing processes; a data processing section configured to cause the data processing processes to be executed; and a scheduler configured to produce a data processing schedule as a data processing procedure of the data processing processes to be executed by the data processing section based on a data processing model obtained by modeling the data processing procedure to be executed by the data processing section. The data processing section causes the processors to execute the data processing processes in accordance with the data processing procedure set in the data processing schedule.
