ABSTRACT:
The invention efficiently determines consistency of a database by a system including a reading section that sequentially reads from the respective segment data included in the database pointers to other segment data, an address recording section that records storage addresses of segment data from which the pointers have been read by the reading section, and a pointer recording section that records the pointers read by the reading section. Then, when segment data is updated in an area in which the pointer reading has been completed, a storage address recorded in the address recording section is modified and a pointer recorded in the pointer recording section is modified. Then, it is determined that the database is consistent on condition that the respective storage addresses recorded in the address recording section coincide with the respective pointers recorded in the pointer recording section.
