    摘要： A system for integrating databases comprises a first virtual table, a second virtual table, a common table, a list, a generating section, and a selecting section. The first virtual table corresponds to a first data. The second virtual table corresponds to a second data. The common table is associated with the first and second virtual tables. The list indicates information about associations between the first and second virtual tables and the common table. The generating section generates two or more access plans from a database query on the common table. The two or more access plans involve at least one of the first and second virtual tables in accordance with the list. The selecting section selects one of the two or more access plans generated by the generating section to be used to execute the database query.

    摘要： A method of controlling access to a database includes autonomously archiving data within a database from a first storage device into a second storage device, according to an archive condition; the archive condition being input in conjunction with the data and being associated with the data; accepting an input of an access command to the database; determining whether data to be accessed in response to the access command input has already been archived in the second storage device based on the access command and the archive condition; and accessing data included in the database or data archived in the second storage device according to the access command based on the determination.

    摘要： An information processor may include a command receiving unit that receives an immediate processing command in which a deletion target to be deleted from the database is conditioned, and a registration processing unit that registers information defining the deletion target into a management data unit. In addition, the information processor may include a deletion processing unit that deletes the deletion target from a database, and deregisters the deleted deletion target from the management data unit. The information processor can also include a data manipulation command processing unit, which, in the case where a data manipulation command having a manipulation target that coincides with a table of the deletion target registered in the management data unit is received, processes the data manipulation command in a state where a condition to exclude the deletion target from the manipulation target is added to the data manipulation command.

    摘要： An apparatus is provided with base table storage sections that store base tables and delta tables for the base tables, a summary table storage section that stores a summary table for storing results of queries to a plurality of base tables and delta information about the summary table, delta data processing sections that insert delta data of the base tables into the delta tables, and a delta computation processing section that generates delta information about the summary table. The delta computation processing section is provided with a generation section that generates delta information about a specified base table on the basis of an update that has been performed for the base table, in a situation where a subsequent update of the specified base table is permitted; and a control section that performs control so that, when a different base table is specified, delta information is generated in a different transaction.

The first virtual table corresponds to a first data. The second virtual table corresponds to a second data. The common table is associated with the first and second virtual tables. The list indicates information about associations between the first and second virtual tables and the common table. The generating section generates two or more access plans from a database query on the common table. The two or more access plans involve at least one of the first and second virtual tables in accordance with the list. The selecting section selects one of the two or more access plans generated by the generating section to be used to execute the database query.
