Recently, thanks to the development of wireless communication technology, disk databases are being
transferred to mobile databases. A mobile based database, unlike disk based databases, uses a NAND
memory for data processing on a low memory capacity and low power batteries. However since the NAND
memory is composed of an erase-before-write structure, problems where too much time and expenses are
spent when recovering from a malfunction arises. So, the BISLD technique was suggested in order to
improve on this problem. The BISLD technique can quickly process data when a problem occurs in the
mobile device by forming its log with a B+Tree directory and a re-do log. However deterioration problems occur where an overhead comes about from using a B+Tree. Thus this paper wishes to suggest an efficient
recovery and logging technique composed of a T-Tree index from a mobile based database. It has also
proven that the overhead reduced during a failure recovery from the suggest technique by a performance
evaluation of the preexisting method and the suggested method.
