    摘要: A pattern finding device of embodiments includes a pattern generator, a pattern storage, a pattern selector, a pattern deleter. The pattern generator generates a group of patterns from data including a plurality of items. The pattern storage stores the group of patterns generated by the pattern generator. The pattern selector selects at least one pattern to be deleted from the group of patterns with reference to an evaluated value indicating a change of an item distribution condition in the group of patterns when at least one pattern which is selected as a candidate is excluded from the group of patterns stored in the pattern storage. The pattern deleter deletes the at least one pattern that is selected by the pattern selector from the pattern storage.

    摘要: According to an embodiment, an information processing system includes a server and a client. The server includes a storage, a receiver, and a storage controller. The storage is configured to store data and its version in a record indexed by a key for identifying the record. The receiver is configured to receive, from the client, a write request including write data, requested key for identifying a record where the write data is to be stored, and a write version that indicates a version of the write data. The storage controller is configured to replace the data and its version in the record identified by the requested key with the requested write data and the requested write version, respectively, if the version in the record identified by the requested key is smaller than the write version.

    摘要: A remote maintenance system includes a maintenance management apparatus connected to a user apparatus and a communication relay apparatus connected to a remote-controlled apparatus. The maintenance management apparatus transmits, to the communication relay apparatus, message data whose destination is unique identification information of a mobile communication network assigned in advance to the communication relay apparatus. The communication relay apparatus notifies the maintenance management apparatus of an IP address that is dynamically assigned to itself upon reception of the message data. The maintenance management apparatus transmits, to the communication relay apparatus, information on remote operation received from the user apparatus whose destination is the notified IP address. The communication relay apparatus relays, to the remote-controlled apparatus, the information on the remote control received from the maintenance management apparatus.

    摘要: A distributed database system accesses data by using management information managed by another data store, and accelerates a timing to update a data record having high access frequency. Thereby the latest data can be easily acquired. A distributed database system according to one embodiment comprises a distributed database including a plurality of nodes that stores data, and a data management device that manages the data stored in the plurality of nodes. Each of the nodes comprises a data storage unit that stores the data related to a time stamp representing a time when the data is stored and a key identifying the data, a data update unit that updates the data, a data sending unit acquires the data stored in the data storage unit, and a data update promotion unit that requests the data update unit to update the acquired data when the acquired data is not latest data.

    摘要: An authentication system according to an embodiment is provided with a service providing apparatus, an IDaaS corporation apparatus, and an authentication providing apparatus. Based on the user ID and SSO request transmitted from the user terminal, the authentication providing apparatus executes authentication processing for the user. If the result of the authentication processing indicates success, the IDaaS corporation apparatus having SSO account information including the SSO account identifier identical to the user ID, permits SSO authentication to be executed for the service identified by the service account identifier included in the service account information associated with the SSO account information. The service providing apparatus transmits information related to the service to the user terminal.

    摘要: According to an embodiment, an information processing system includes a client apparatus and three or more server apparatuses that each store data. The server apparatus includes a first storage, a receiver, a generator, a selector, a transmitter, and a changer. When the number of requests indicating identical changes among the requests of the data candidates is larger than a first threshold, the selector selects one of the requests indicating identical changes, and sets the state of the selected request to a second state. The transmitter transmits the data candidate including the selected request to one or more server apparatuses. When the number of requests in the second state among the requests of the data candidates is larger than a second threshold, the changer updates the history data and changes the data by using one of the data candidates including the requests in the second state.

    摘要: According to an embodiment, an ordering device determines a processing order of pieces of data in each computer in a multiplex system. The device includes a preliminary elector and a confidence elector. The preliminary elector is configured to generate, when a vote having the current order number, the current round number, and a nominated state is acquired from a primary computer, a vote that includes data included in the acquired vote, the current order number, a round number following the current round number, and a winning-assured state. The confidence elector is configured to determine, when a vote having the current order number, the current round number, and the winning-assured state is acquired for identical data from each of a threshold or more of the computers, data included in the acquired vote to be data to be processed at the current order number.
