A multiplicity adjustment agent collects request information database from a sub-system including an element of a system to be monitored. An individual sub-system's multiplicity adjustment server sorts and merges request information collected from each sub-system for each element/request path. An integrated multiplicity analysis server calculates a necessary multiplicity on the basis of the request information.

Multiplicity adjustment system and method

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.

Secure multi database system including a plurality of database devices

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.

Method and system for detecting tables to be modified

A document management system of managing as inter-document relation information a plurality of keywords collected as a set for each document template type and managing link among said keywords includes the document file entry and update steps of selecting at least one of keywords based on a document template type in the inter-document relation information; linking the selected keyword with the document file; and detecting a document file influenced by the document entry and update by using the link between the selected keyword and the document file and the inter-document relation information.

Document management method and document management system

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.

Method for changing database construction information

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.

Spatial information search system

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.

Link information maintenance management method

Representative item information concerning an item name represented on a form, parts control information for controlling a part or input/output area forming a display screen for inputting data to a database, and data attribute information including field name and data type referred to in defining a table in the database, are created for each item name beforehand. In accordance with an input from a user for image information of the form inputted beforehand, there is generated link information which includes positional information for distinguishing a position on the image information and sub referential information for distinguishing a field of the database. On the parts control information, a part is displayed on the image information displayed on a display device. A table of the database is defined on the basis of the data attribute information.
