Abstract
A method of verifying the consistency in a hierarchical database includes: generating a pointer record by acquiring a reference point stored in the hierarchical database and associating a first reference point identification value determined from a storage location of the reference point with pointer information retained at the reference point; generating a segment record by acquiring a segment stored in the hierarchical database and associating verification data with a retention address of the acquired segment, the verification data giving a second reference point identification value in connection with the calculation module, the calculation module calculating, for a segment in the hierarchical database, a reference point identification value used to identify a reference point which points to the segment; and verifying the consistency of a chain formed in the hierarchical database from the reference point to the segment by comparing the segment record with the pointer record.
