According to this study, if software has been developed in which the data transferring was based on the conceptual model and the MARC’s data that already exists in the National Library's bibliographic database, these relationships will not be transferable. Withal, in this study the relationships on consistent FRBR and MARC concluded with an intelligent mind and the machine is unable to detect them. The results of this study showed that the relations which conveyed from MARC to FRBR, was about 47/70 percent of the MARC fields, in other hand by FRBR to MARC with the use of all intelligent efforts, and diagnosis of MARC relationships, only 31/38 percent of the relations can be covered through the MARC.
