Abstract: There is provided a technique capable of executing a predetermined processing while continuing a database processing. Firstly, the database to be operated is switched from the main database to a duplicate database. The predetermined processing is executed to the main database which becomes the non-operation mode by the switching. Next, a database access request is distributed to the duplicate database which becomes the operation mode by the switching, thereby performing the database processing. Update information indicating the content of the update processing performed to the duplicate database is output. The output update information is reflected on the main data base for which the predetermined processing has been executed. After this, the database to be operated is switched from the duplicate database to the main database.

Abstract: In response to requests for I/O processing sent from a computer, I/O which should be processed at a priority is enabled to be processed without being affected by other processing, by classifying I/O into those to be processed at a priority and those not to be processed at a priority.

From the downloaded data is extracted information indicating links between two databases, a detailed description of each data, and sequence data for homology search, which together constitute an index. The thus extracted index 15 is distributed to a user facility, where a user 18 conducts a search using the distributed index.

Abstract: The invention provides information concerning records that cannot be retrieved on a search path among databases when the retrieval of search keys for other related databases and records is carried out in a plurality of databases in a chain-reactive manner. In the course of retrieving search keys and records in a chain-reactive manner up to a terminal database, information for identifying a group of search keys and a group of records retrieved through a series of retrieval processing is outputted in one line or one column of a table. When the record retrieved from a certain database in the chain-reactive search procedure does not contain a search key to be entered into a subsequent database, information for identifying a record that does not contain the search key and information for identifying a database having the record is outputted.
