Abstract
The present invention relates to an apparatus and a method for managing a buffer having three states on the basis of a flash memory and, more specifically, to an apparatus and a method for improving the performance of a database management system (DBMS) on the basis of the flash memory and a use life span of a storage device by reducing a writing operation for a flash memory device in which the writing operation is very slow in comparison with a reading operation, through an efficient buffer managing method and a new index node split policy. To this end, the buffer management device having three states on the basis of the flash memory according to an embodiment of the present invention comprises: a buffer memory unit; a list management unit; a buffer memory management unit; and a log buffer unit.
