Latest Patents
Matsuda's latest patents include a database system management method, a database system, a database device, and a backup program. The first patent describes a method for managing a database system that includes a primary database device, which changes its memory content based on commands from any business terminal device through a network. Additionally, a secondary database device stores the same memory content as a backup. This method involves creating and storing a logical log that correlates command content with memory content every time a process is executed. It also includes creating a physical log that correlates position information about the changed portion, the updated memory content, and the class of the process. Furthermore, it stores command specifying information corresponding to the physical log each time a physical log is created.
The second patent focuses on a control device at a main center that ensures updates in an operational database device at the main center are also reflected in a sub-center's operational database device. This is achieved by generating and transmitting a differential log file to the control device at the sub-center. Upon receiving this file, the control device updates the operational database device based on the log information and accumulates it in a recovery log file.
