Title:
EXTRACTING METHOD FOR PROGRAM LOGIC USING TWO ITEM OBJECT
Document Type and Number:
Japanese Patent JP3153371
Kind Code:
B2
Abstract:
PURPOSE: To set a work for easily extracting the logic of a complicated existing program, for arranging extracted logic so that it car be used again and for generating new program structure to be efficient.
CONSTITUTION: The existing program is inputted (201), and the respective transactions of the program are analyzed into respective data elements. The analyzed data elements are expressed by a pair of the data elements (two items objects) and they are substituted for a capsule constituted by the inherent process (202). The overlap of information made into the capsule is removed (203), and it is stored in data accumulation structure which can be re-used. Program logic is extracted from information which is made into the capsule (205).
