| 20100241790 | METHOD OF STORING DATA INTO FLASH MEMORY IN A DBMS-INDEPENDENT MANNER USING THE PAGE-DIFFERENTIAL - The present invention proposes an effective and efficient method of storing data called page-differential logging for flash-based storage systems. The primary characteristics of the invention are: (1) it writes only the page-differential that is defined as the difference between an original page in flash memory and an up-to-date page in memory; (2) it computes and writes the page-differential only when an updated page needs to be reflected into flash memory. When an updated page needs to be reflected into flash memory, the present invention stores the page into a base page and a differential page in flash memory. When a page is recreated from flash memory, it reads the base page and the differential page, and then, creates the page by merging the base page with its page-differential in the differential page. This invention significantly improves I/O performance of flash-based storage systems compared with existing page-based and log-based methods. | 09-23-2010 |

| 20090164524 | SHADOW-PAGE DEFERRED-UPDATE RECOVERY TECHNIQUE INTEGRATING SHADOW PAGE AND DEFERRED UPDATE TECHNIQUES IN A STORAGE SYSTEM - Disclosed herein is a recovery method in a storage system that integrates shadow page and deferred update techniques. In our invention, for update operations that occur during a transaction, update of a page in the buffer is not immediately reflected to the database, but is deferred until the transaction is committed. Instead, we store the updated buffer page in the log volume in the unit of a page. When reading a page that does not exist in the buffer from the disk, we read the up-to-date page from the database or from the log volume. Here, the log table index is used to determine whether the up-to-date page exists in the database or in the log volume and to identify the position of the page stored in the log volume if the up-to-date page exists in the log volume. The proposed invention has the following excellent advantages. It is simple and efficient because the deferred update file does not have to be additionally accessed for correct query processing. Besides, there is no performance degradation because the position of an updated page in the database is not changed, and thus, the original clustering of logically related data is preserved. | 06-25-2009 |
