An Implementation Methodology for Business Systems Based on Unidirectional Constraint Propagation -- A Case Study of Local Tax Processing --

Abstract (in Japanese) (See Japanese page) 
(in English) ICT systems for business applications must accept not only basic business work-flows but also modification of the formerly -inputted data. This modification changes the old calculated output values. The above situation requires a huge program and severe maintenance cost. This paper argues that this situation is caused by a semantic gap between business rules and superficial business flows. To solve this problem, we propose a new methodology to implement application systems based on the unidirectional constraint propagation from input to output. We regard business rules as constraints between input and output and implemented a prototype system with about 5,700 lines in an object-oriented programming language. The system supports 23 kinds of local taxes (but some detailed tax-value calculation routines are omitted). Our evaluation shows that the proposed methodology results in very compact and well-structured codes. Also, the prototype system performs such complex business flows as the modification of formally -processed input and output without additional codes.
