Abstract: In a computer system for performing linkage control of information between organizations, scenario management information for managing a scenario in which trigger information related to an event related to a user is associated with a target organization as a target of the linkage control accompanying an occurrence of the event is held, and when receiving information from an arbitrary organization, an arithmetic device searches for the scenario including the received information as the trigger information, identifies the target organization based on the scenario and the received information, and transmits shared information generated from the received information to the target organization.

Abstract: A design support system that executes design support of an architecture of a cloud deployment system generates architecture candidates in the case of sharing of resources by new systems newly deployed on a cloud and operation systems which are operating on the cloud and architecture candidates in the case of non-sharing of the resources. For the architecture candidates in both the cases of sharing of the resources and non-sharing of the resources, architecture candidates meeting a non-function requirement of an operation system and a non-function requirement of a new system are determined as architectures deployed on the cloud.

Abstract: A data processing unit required for the data processing is started and a data processing unit not required for the data processing is stopped to change a part of the data processing settings or to add a new data processing setting without stopping the multi-stage data processing, and when the multi-stage data processing is executed, a rear-stage data processing unit reads the tag assigned in a front-stage data processing unit to discriminate the data processing unit that executes the data processing.

Abstract: The data processing management system includes a queue deployment system that deploys a queue with a processing description of stream processing having a branch instruction being an input. The queue deployment system designates processing to be preferentially executed for the processing description, measures throughputs in respective processing after the branch instruction, and obtains branch proportions that at which the respective processing after the branch instruction is executed. The queue deployment system then computes deployment costs in a case of deploying a queue between the branch instruction and the respective processing after the branch instruction, for combinations of the respective processing after the branch instruction using the throughputs and the branch proportions, and outputs a queue deployment pattern for preventing a decrease in a throughput of the processing to be preferentially executed among the respective processing after the branch instruction.

Abstract: A device management system comprises a data collection server and edge server including an adapter that transfers a device-related data set of an industrial device. Upon receipt of the device-related data set and when the data collection server is unable to specify a row that both adapter identification information of the device-related data set and device identification information match, in a devices list table and when the data collection server is able to specify a location name of a row that only the adapter identification information matches, in the devices list table, the data collection server is configured to generate/assign a new unique device identification ID based on the specified location name, the locations list table, and the devices list table. The data collection server associates the new unique device identification ID with the received device-related data set, and then stores the device-related data set in the data accumulation section.

Abstract: A data processing system includes an analysis part cache that caches data of a database, a data processing development module that is used by a developer and develops analysis processing for data analysis, a data processing module that is used by the developer and performs data analysis by executing analysis processing, a cache management module that sets an update constraint input from a DB administrator regarding cache update from the database in the analysis part cache, and an update determination module that determines whether or not cache update is possible based on the update constraint, and when cache update is requested, the update determination module executes the requested cache update if cache update is possible in the determination.

Abstract: This invention is intended to process data synchronization more efficiently. Disclosed is a data synchronization system comprising: an all records fetching unit that fetches all records of synchronization target data, i.e., data specified as a target of synchronization, from a first device that is a source of synchronization; one or more storage units to prestore synchronization destination data, namely, data that is now retained on a second device that is a destination of synchronization and store synchronization target data fetched by the all records fetching unit; and a difference extraction unit that identifies difference to be reflected in the data on the second device by using the synchronization destination data and the synchronization target data, makes identified difference reflected in the data on the second device, and, after the reflection, updates the synchronization destination data based on the synchronization target data.

Abstract: A data collection server that collects and converts data has a data processor that executes shaping processes to shape collected data, sets a data processing flow based on the shaping processes, sets information of an execution environment of the shaping processes and converts the processing flow based on the information of the execution environment. The processor accepts setting inputs of first and second flags before and after the plurality of shaping processes and performs an integrated shaping process for collectively executing the plurality of shaping processes between the first and second flags when set. The processor also updates information of the execution environment based on execution contents of the integrated shaping process.

Abstract: Allocation of resources is performed in which the performance of the services of each tenant can be maximized in a multi-tenant environment in which a plurality of tenants exist in which a plurality of data processing functions operate. The computer system calculates a first allocated resource amount to be allocated to each tenant based on the requested resource amount requested by each data processing function of each tenant, and calculates the second allocated resource amount to be allocated to each data processing function of each tenant based on the requested resource amount that each data processing function of each tenant requests and the first allocated resource amount of each tenant, and allocates resources to each data processing function of each tenant based on the second allocated resource amount.
