In "parallel DB access" in which the original of a database (hereinafter, referred to as DB) is copied to a plurality of computers to create a replicated DB, the replicated DB is edited by the computers in parallel, and the result is reflected in the original DB, the tables are edited in parallel, and a table which defines the items of the tables is also targeted for the parallel editing. After the confirmation of the editing of an item table by means of the validation of the editing, if necessary, the item table performs the reconstruction of the original table which defines the items. This enables not only the parallel editing of table contents, but also the editing of the addition, deletion, modification, or the like of an item of a table to thereby share the result between the computers.
