    摘要: A memory system includes a volatile first storing unit, a nonvolatile second storing unit, and a controller. The controller performs data transfer, stores management information including a storage position of the data stored in the second storing unit into the first storing unit, and performs data management while updating the management information. The second storing unit has a management information storage area for storing management information storage information including management information in a latest state and a storage position of the management information. The storage position information is read by the controller during a startup operation of the memory system and includes a second pointer indicating a storage position of management information in a latest state in the management information storage area and a first pointer indicating a storage position of the second pointer. The first pointer is stored in a fixed area in the second storing unit and the second pointer is stored in an area excluding the fixed area in the second storing unit.

    摘要: A controller includes an identification information management table that manages identification information indicating, for each of addresses in second-management unit, whether one or more data in first management unit belonging to the addresses is stored in the second or the third storing area. When the controller executes a process of flushing data from the first storing area to the second storing area or the third storing area, the controller updates the identification information in the identification information management table. The controller executes a process of reading data from the second storing area or the third storing area by referring to the identification information. As a result, the speed of searches conducted in the management table is increased.

    摘要: An information generation system includes: an acquisition unit to acquire a set of records, each f which indicates a correspondence relation between a setting condition and a processing result for each processing, a generation unit to generate display information in order generate a display image based on the set of records, and a control unit to control a display unit so as to display the display image based on the display information. The display image includes the first area and the second area. Setting condition axes are displayed on the first area. Processing result axes are displayed on the second area. Value objects indicating concrete values of the setting condition are displayed at the setting condition axes. Value objects indicating concrete values of the processing result are displayed at the processing result axes. Between the value objects, relation objects indicating correspondence relations are displayed.

    摘要: A data search system is configured to: generate a first data set including a plurality of records, in which a first column is used as a reference column, and clustering is performed for each predetermined range of the first column to generate first clusters; generate a second data set including the plurality of records, in which a second column is used as the reference column, and clustering is performed for each predetermined range of the second column to generate second clusters; cause a memory device to store therein the first date set and the second data set; generate index information in which information indicating the reference column, information indicating the predetermined range, and a memory area of the clusters are associated with each other; read out the cluster from the memory device based on the index information; and extract data matching the search condition from the read cluster.

    摘要: A sever communicates with a terminal device and a data management device. The terminal device displays a visualization screen. The data management device generates aggregate data in which original data is aggregated. The server includes one or more circuitry configured to receive customization information indicating setting related to the visualization screen from the terminal device, cause a storage to store therein screen configuration information indicating a screen configuration of the visualization screen based on the customization information, create a request for generating the aggregate data based on the customization information and the screen configuration information, and transmit the request to the data management device.
