Abstract
PURPOSE: To attain the highly speedy retrieval by defining the referring relation construction of a table and executing the retrieval in accordance wit the defined table referring relation construction.
CONSTITUTION: A defining part 4 for a table referring relation construction defines the table referring relation construction among respective tables stored in a table data storing part 2 based on an input from a displaying input/output part 1. A table referring relation data preparing part 6 prepares the table referring relation data in accordance with a table referring relation construction based on the input from the input/output part 1 or the table data stored in the table data storing part 2, and a retrieving part 8 for a table referring relation data executes the retrieval of the table data with the table referring relation data by the retrieving procedure in accordance with the table referring relation construction based on the input from the input/output part 1. Thus, since the retrieval can be executed in accordance with the defined table referring relation construction, it is not necessary to prepare a complicated instruction for each retrieval instruction, and since the retrieval is executed by the table referring relation data, the highly speedy retrieval can be executed.
