This Disclosure is a solution to check consistency among Data Flow Diagrams (DFDs) , and between DFD and IPO (Input-Process-Output diagram), and make Read/Write matrix of Data Store (DS) vs DFD Process. Input information is text style Repository of DFD , text style Repository of IPO , Notation and DS Notation. Output are Check Result of DFDs consistency between upper and lower, Check Result of consistency between DFD and IPO, and Read/Write matrix of DS vs DFD Process .Text style Repository of DFD includes DFD Level , DFD Number DFD Name , near-side DS#/External Entity(EE)/Process Number DF Number far-side DS#/EE/Process Number and so on.Text style Repository of IPO includes in-side DF Number out-side DF Number Process Number and so on. The rough flow charts are as follows(fig-1,fig-2,fig-3,fig-4).
