The number of clusters to which the data entities are assigned may correspond to the determined value.

Abstract: A data partitioning apparatus receives stream data and stores with previous-and-subsequent information that specifies data previous and subsequent to the data. Then, for groups, each of which contains the data that are stored and that are partitioned into the number of the groups, the data partitioning apparatus stores top information specifying data located at the top in a corresponding group and end information specifying data located at the end in the corresponding group. Then, when new data is stored, the data partitioning apparatus specifies data previous and subsequent to the new data and stores the new data by associating it with the previous-and-subsequent information that specifies the data previous and subsequent to the new data. Then, when data is inserted, the data partitioning apparatus updates information for each group such that the difference between the number of data belonging to each group is equal to or less than one.

Abstract: An electronically stored financial document is either maintained in a first storage system when a parameter associated with the document is greater than a pre-selected parameter or in a second storage system when the parameter associated with the document is less than or equal to the pre-selected parameter. A request for a stored financial document is received and the requested financial document parameter is compared to the pre-selected financial document parameter to determine if the electronically stored financial document's parameter is more than, less than, or equal to the pre-selected parameter. In processing the request, a processing unit electronically accesses one of the storage systems in response to the comparison of the pre-selected parameter to the electronically stored financial document's parameters. After accessing the appropriate storage system, the requested electronically stored financial document can be reproduced, and/or distributed.

Abstract: In a data processing method, a storage apparatus stores one or more results of a second process, corresponding to input data sets processed in the past. When a first input data set is designated, a search unit searches the storage apparatus for a result of the second process, corresponding to a second input data set having an overlapping part with the first input data set. A data processing unit acquires a result of the first process, corresponding to differential input data that is included in the second input data set but not included in the first input data set, and generates a result of the second process, corresponding to the first input data set, by removing the effect of the differential input data from the result of the second process found as a result of the search, using the acquired result of the first process.

Abstract: A journaling subsystem on a mobile device stores event data related to applications or other subsystems running on the mobile device. The event data can be stored and indexed in a journal database so that a timeline of past events can be reconstructed in response to search queries. In some implementations, a timeline can be reconstructed with markers on a map display based on search results. When the user interacts with a marker on the map display, the event data collected by the mobile device is made available to the user.
