  • Patent number: 9870404
    Abstract: When plural processing programs for generating post-processing data which is a source of services to be provided are present, a relationship between post-processing data and a data group which is a source of the post-processing data is managed. The processing units acquire pre-processing data, execute given processing, and generate post-processing data as a result of the processing. At an opportunity to acquire the pre-processing data, a process ID indicative of ordering of the acquisition, and not updated before and after the given processing is allocated to acquired pre-processing data. The generated post-processing data is stored, and in extracting the post-processing data satisfying the given data search condition, the post-processing data having a process ID equal to or before the process ID that is latest in the post-processing data and oldest among the respective processing units is extracted from the post-processing data that satisfies the data search condition.

  • Publication number: 20160217192
    Abstract: A search system using a table search server and a file search server as transmission destination candidates for search queries, wherein search speed is assumed to be higher for a search in the form of file data than for table data, the table data is converted to file data and stored in the file search server. Created are a search query history management table for accumulating and depositing search query history, and a characteristic determination rule management table for managing the rules of determining that the search speed is higher for a search made in the form of file data than for table data. The search system applies the characteristic determination rules to the search query history and specifies the table data. The search system acquires the specified table data from the table search server, converts the data to file data, and stores the data in the file search server.

  • Publication number: 20160012065
    Abstract: The present invention provides a system for realizing both the operation of archive and sharing of contents capable of maintaining a privacy policy of critical data. In order to realize the system, a disclosure condition to a data reference destination and a data conversion method of the file data are designated, and only the file data matching the disclosure condition is provided to the data reference destination by anonymizing the file data via the data conversion method. When the disclosure condition or the data conversion method is changed, an already disclosed file data is deleted, or replaced with the file data subjected to data conversion after the change.

  • Publication number: 20150331916
    Abstract: A computer system including a shared file server manages the access to file data for performing access to the file data accurately and efficiently. This computer includes a plurality of first name spaces to which is assigned an access path to data stored in a storage area, and a name space to which is assigned a path corresponding to the access path and which is different from the first name spaces. When the access paths generated in different first name spaces are the same, the corresponding paths which correspond to the same access paths are changed into mutually different paths. Moreover, by assigning a path corresponding to the data to be analyzed, it is possible to efficiently access the requested data among a large amount of data. In addition, the sorting of the corresponding paths is changed according to the load of the computer storing the data.
