COST COMPUTING SYSTEM, COST DATA INPUT SYSTEM, ITS PROGRAM, DATA STRUCTURE, AND RECORDING MEDIUM WHERE THEY ARE RECORDED

摘要

Cost data is associated with a transaction and the work item of the work performed to execute the transaction, and they are stored. Out of the cost data, transaction data representing the transaction associated with cost data is associated with the work item of the work and given an Elements-Outsourced-from-Third-Party attribute indicating the transaction data representing a subcontraction transaction when the work indicated by the cost data brings about a subtraction transaction. If the transaction data is given the attribute, a TC computing section (71) totalizes the costs of the subcontraction transaction when computing the cost of the transaction. With this, transactions concerning large to small various economic activities and including indirect works are expressed by a unified data structure and processed. A cost computing system realizes above process.
