Abstract
Fixed-length data () contained in a database () are segmented into a number of pieces of data that are searchable at a time and searching is performed at high speed. As means for it, a pointer table (), a secondary pointer table, a local table, and a fixed-length-data table are provided, and when more segmentation is required, a table having a numeric-value comparing function is further provided. As means for performing efficient configuration/management of the tables and for performing management that does not interfere with a search operation, an empty-house table (), an empty-room table (), a room-management table (), and a structure-management table () may be provided.
