JAXA has a plan to develop the system which integrates EFD and CFD. This system has a database which stores both EFD data and CFD data. The user can obtain advanced information by searching, visualizing, and comparing EFD data and CFD data stored in the system. We report the system configuration, issue, and data format. Although the details of data format will be decided in the near future, we report an example about containing data in a data format.
