Publication number: 20070005619Abstract: In an MD schema definition modifying process for specifying tables to be modified in terms of addition of columns or the like when modification such as addition of a dimension is applied to an MD schema in a BI system having a fixed model such as a data model, tables to be modified in terms of addition of columns or the like are specified on the basis of information of modification such as addition of the dimension to the MD schema. In an extraction process of modification candidate tables, all combinations of tables and columns to be modified in terms of addition of columns or the like are output. In a decision process of modification target tables, a combination of tables to be modified can be output.Type: ApplicationFiled: September 12, 2006Publication date: January 4, 2007Inventors: Hitoshi Ashida, Mitsuhiko Yoshimura, Norifumi Nishikawa, Masashi Tsuchida

Patent number: 7152067Abstract: A definition tool of the present invention declares columns which are concealed in external tables to a multi-database server. The multi-database server controls a decomposition and an execution of query messages such that the multi-database server does not perform an arithmetic using the concealed columns. The external database server encrypts the data of concealed columns in tables of query result tables. The multi-database server designates a range to be decrypted at the time of acquiring and integrating respective result tables. A client program acquires an integrated result table and decrypts the designated range. Since the data encrypted by the external database server is decrypted by and is referred to the client program, it becomes difficult for the multi-database server to refer to a content of the concealed columns.Type: GrantFiled: August 26, 2004Date of Patent: December 19, 2006Assignee: Hitachi, Ltd.Inventors: Yuichi Yagawa, Mitsuhiko Yoshimura, Akira Maeda, Shigetoshi Hayashi

Patent number: 7080084Abstract: Upon modifying a database system, a modification range is managed on the basis of a pattern name, a variable name associated therewith, an influence range detection start destination based on the variable name, and an influence range detection result as modification pattern information. And a variable value is registered according to a pattern selected based on the modification pattern information, a modification object on a plurality of middleware bases is detected as influence range information on the basis of the variable value entered in association with a modification pattern, and a schema definition of a database and a group of commands for data transformation are modified in accordance with the modification contents using the influence range information.Type: GrantFiled: January 30, 2003Date of Patent: July 18, 2006Assignee: Hitachi, Ltd.Inventors: Mitsuhiko Yoshimura, Norifumi Nishikawa, Hitoshi Ashida

Patent number: 6882994Abstract: The present invention provides techniques for answering a user's query to a database system. An embodiment provides a database querying method in which a first data item is obtained from a Data Base Management System (DBMS) database table in response to a query request. A second data item is obtained by referencing a DBMS updated log file, having log data associated with the first data item, for example a timestamp. The first and second data items are then integrated and returned as an integration result to the query request. In one embodiment the first and second data items are integrated in a virtual table in accordance with a predetermined business rule.Type: GrantFiled: March 26, 2001Date of Patent: April 19, 2005Assignee: Hitachi, Ltd.Inventors: Mitsuhiko Yoshimura, Yuichi Yagawa, Shigetoshi Hayashi, Norifumi Nishikawa, Keiichiro Inaba

Patent number: 6708183Abstract: It is an object of the present invention to provide a scheme for distributing spatial information between information providers and information users. To achieve this object, the present invention creates a corresponding index for each spatial information. The index includes information related to a position included in spatial information, and data related to a storage location of the spatial information. This index also includes (1) a source ID for uniquely identifying spatial information; (2) coordinate translation values which are parameters used to correspond certain spatial information to other spatial information; and (3) when the spatial information including this index was created by referencing other spatial information, an underlay diagram specifying ID represented by the source ID possessed by the referenced spatial information, or the like.Type: GrantFiled: February 18, 2000Date of Patent: March 16, 2004Assignee: Hitachi, Ltd.Inventors: Maki Mori, Koichi Homma, Shuji Kitazawa, Hiroshi Yajima, Yoshiaki Yoshikawa, Mitsuhiko Yoshimura, Chigusa Hamada

Publication number: 20020055921Abstract: There is provided units for managing and defining a virtual table access privilege, an integration-target-DB access privilege, and access-privilege mapping information for making the connection between them. A processing unit for performing the access-privilege decision on the level of the virtual tables by using the definition contents of the information, and a processing unit for converting the virtual table access privilege into the integration-target-DB access privilege are provided. System structuring working on the AP (application) side and that on the integration-target DBMS side can be carried out easily in parallel to reduce the load imposed on the system structuring working.Type: ApplicationFiled: March 12, 2001Publication date: May 9, 2002Inventors: Mitsuhiko Yoshimura, Yuichi Yagawa, Shigetoshi Hayashi, Norifumi Nishikawa

Patent number: 6381612Abstract: A link information management method which is capable of reducing the number of steps of a link maintenance processing of link information indicating a corresponding relationship between geographical information in a geographical information system and attribute information. To realize the method, geographical information are compared and judged by translating first geographical information based on corresponding points judged as the same points inputted on first and second geographical information by an operator. Further, update days of link information and attribute information are compared and judged, and current link information which causes the second geographical information and the attribute information to be correlated with each other is generated based on the compared and judged results of the link information and the attribute information. Then, attribute information and a closed area on the second geographical information are displayed by using the current link information thus generated.Type: GrantFiled: June 1, 2001Date of Patent: April 30, 2002Assignee: Hitachi, Ltd.Inventors: Mitsuhiko Yoshimura, Maki Mori, Hiroyuki Okuda, Yoshiaki Yoshikawa
