摘要： The system manages at least a database in multiple database storage units, and the database is duplicated for redundancy. The system maintains the database redundancy for security. The system enables the maintenance and reorganization of the database storage units without interrupting the on-going operations involving the access to the database storage units. The non-stop ongoing database access is available by allocating a pair of a main storage unit and an intermediate storage unit that maintains the substantially identical data. During certain predetermined operations, the main storage unit is being dedicating to the on-going transactions while the intermediate database storage unit is manipulated to contain data that corresponds to a specified time. For example, the content of the intermediate storage is subsequently copied or used to update another database. When the above duplication or incorporation is completed, the intermediate storage unit is updated for the transactions that have taken place during the above operations to be synchronized with the main storage unit.

摘要： A database management system for executing database operations in parallel by a plurality of nodes and a query processing method for it are described. The database management system contains a decision management node for deciding a distribution node for retrieving information so as to analyze a query received from an application program, generate a processing procedure for processing the query, and execute the process and a join node for sorting, merging, and joining the information retrieved by the distribution node. When the query process is executed, the distribution node decided by the decision management node retrieves the information to be processed and the join node decided by the decision management node also obtains the result for the query from the retrieved information. The query result is outputted from an output node and transferred to the application program.

摘要： In a computer system including a main memory and an expanded memory for expanding said main memory logically, a program operating on a virtual memory space, which is managed by the virtual memory management of an operating system, for managing the input/output of the data on an external storage device by using an I/O buffer has a function to manage the I/O buffer secured on the expanded memory, so that the I/O processing for the external storage memory may be reduced by either saving the data, if necessary, of the I/O buffer on the virtual space into the I/O buffer on the expanded memory or restoring the same to the I/O buffer on the virtual space, whereby the I/O buffers can be efficiently utilized.
