Abstract: A control method implemented by a computer configured to control a database that includes an aggregate item that records an aggregate value of transaction volume included in transaction data recorded in a blockchain, the control method including: obtaining a plurality of the transaction data recorded in the blockchain; specifying, for each of a plurality of second users who are transaction partners with a first user associated with the aggregate item, a transaction time with the first user on a basis of the plurality of transaction data; classifying the plurality of second users into a plurality of groups on a basis of dissimilarity of the transaction time; and generating the aggregate item for each of the groups in the database.

Abstract: An operational control management method of determining a possibility of parallel execution of multiple operational controls that are included in a workflow, in which a computer performs processing includes judging whether a first operational control that is to be executed next and a second operational control that follows the first operational control are detailed determination targets, based on operation categorization information that results from categorizing each of the multiple operational controls based on an operation target and operation content; and determining a possibility of parallel execution based on relationships of the first operational control and the second operational control to the operation target and on operation situations of operation targets, with which the first and second operational controls are associated, in a case where the first operational control and the second operational control are the detailed determination targets.

Abstract: A non-transitory computer-readable storage medium storing a control program that causes a computer to execute a process, the process including obtaining, for each of a plurality of job flows to which coincident input data is inputted, data excluded from the coincident input data of each of the plurality of job flows by a data extraction process or information specifying the excluded data, each of the plurality of job flows defining a plurality of processes including the data extraction process to be executed, and determining whether the plurality of job flows whose output data are coincident each other are aggregated or not based on the excluded data or the information specifying the excluded data.

Abstract: A first executing unit executes, among tasks included in a first workflow, a first task group including one or more tasks using a resource. When a task included in the first task group is stopped, a rollback processing unit restores the resource to its former state prior to the execution of the first task group. After the resource is restored to the former state prior to the execution of the first task group, a second executing unit starts executing, among tasks included in a second workflow, a second task group including one or more tasks using the resource.

Abstract: A control unit of a workflow control apparatus identifies, among tasks included in a plurality of workflows, tasks using the same resource based on workflow definition information, and determines the execution sequence of the identified tasks based on the content of each of the identified tasks defined in the workflow definition information. The control unit identifies, among the identified tasks, one or more tasks whose execution is omissible based on the content of each of the identified tasks and the execution sequence of the identified tasks.

Abstract: A non-transitory computer-readable storage medium storing a control program that causes a computer to execute a process, the process including obtaining, for each of a plurality of job flows to which coincident input data is inputted, data excluded from the coincident input data of each of the plurality of job flows by a data extraction process or information specifying the excluded data, each of the plurality of job flows defining a plurality of processes including the data extraction process to be executed, and determining whether the plurality of job flows whose output data are coincident each other are aggregated or not based on the excluded data or the information specifying the excluded data.

Abstract: A device includes: a memory configured to store a condition of exclusive execution for a plurality of processes, and execution time ranges of each of one or more modules, the execution time ranges indicating from a shortest estimation time to a longest estimation time regarding; and a processor configured to estimate an entire execution time by executing estimation processing so as to cause simulation of the estimation processing to progress, the estimation processing including: generating one or more cases, for each of the plurality of processes, in order of the one or more modules based on the execution time ranges, determining whether there is a possibility that exclusion waiting occurs based on the condition, for each of the one or more cases, and setting the exclusion waiting for a certain case in which it is determined that there is the possibility, from among the one or more cases.

Abstract: A exclusion control method includes setting, for at least one or more operation information defining operations for an information processing apparatus and being included in a plurality of work flow information that indicate operation procedures, exclusive sections that indicate units of exclusion control performing an exclusive lock, calculating priorities of the exclusive sections using operation importance level information that indicate importance levels of the operations according to types of the operation information and operation urgency level information that indicate an urgency levels of the operations, when the operations are executed based on the operation information corresponding to the exclusive sections of the plurality of workflow information, and executing the exclusion control in the exclusive sections for a plurality of workflow based on the priorities, when a competitive regarding the exclusive lock occurs between the exclusive sections.

Abstract: A control unit of a workflow control apparatus identifies, among tasks included in a plurality of workflows, tasks using the same resource based on workflow definition information, and determines the execution sequence of the identified tasks based on the content of each of the identified tasks defined in the workflow definition information. The control unit identifies, among the identified tasks, one or more tasks whose execution is omissible based on the content of each of the identified tasks and the execution sequence of the identified tasks.

Abstract: A first executing unit executes, among tasks included in a first workflow, a first task group including one or more tasks using a resource. When a task included in the first task group is stopped, a rollback processing unit restores the resource to its former state prior to the execution of the first task group. After the resource is restored to the former state prior to the execution of the first task group, a second executing unit starts executing, among tasks included in a second workflow, a second task group including one or more tasks using the resource.

Abstract: A exclusion control method includes setting, for at least one or more operation information defining operations for an information processing apparatus and being included in a plurality of work flow information that indicate operation procedures, exclusive sections that indicate units of exclusion control performing an exclusive lock, calculating priorities of the exclusive sections using operation importance level information that indicate importance levels of the operations according to types of the operation information and operation urgency level information that indicate an urgency levels of the operations, when the operations are executed based on the operation information corresponding to the exclusive sections of the plurality of workflow information, and executing the exclusion control in the exclusive sections for a plurality of workflow based on the priorities, when a competitive regarding the exclusive lock occurs between the exclusive sections.
