ABSTRACT:
A plurality of table-formatted data is joined by dividing each table-formatted data into one or more information blocks consisting of a value list containing item values in the order of item value numbers corresponding to item values belonging to a particular item and a pointer array containing pointer values specifying item value numbers in the order of uniquely-defined record number. When joining a plurality of table formats, equivalent items between the table-formatted data are found and value lists contained in the information block concerning the equivalent items are compared and the two value lists are made equivalent, then data of one of the table formats is sorted according to a key item and using the array obtained in this process, calculation is performed to obtain addresses indicating storage positions of record numbers of table-formatted data and other table-formatted data. Using the calculated addresses, joined table-formatted data is displayed.
