Abstract
A database management system is provided to reduce the process time required for data sharing between the server process and the client process. When the client process sends the data reading command to the server process, the server process reads the page specified by the command from the database file, writes the page in the sharing memory device that includes the mapped file and the page buffer and sends the offset that specifies the page within the region in the mapped file to the client process. The client process maps the logic address of the access space in its process to the region specified by the offset to enable accessing of the page written in the page buffer.
