Abstract
A database management program capable of joining three or more tables in a manner that the storage capacity of a memory is more efficiently used. The database management program is configured (programmed) as a program that creates some working tables (WT2-WT4) which hold the information (record identifiers in each table) with which a table in which two tables are joined can be created, and then, by collecting required item values from each table based on the information in the working tables, creates the table whose creation is instructed.
