Abstract: At present, on the basis of microservice, capabilities and applications of a monolithic integrated system are transitioned to a component system and rebuilt. However, the application of microservice to a shared database has not sufficiently been under study. A system building assisting apparatus of the present invention uses, in building of a component system, access history aggregation table indicating access history of access to a database for a production control system corresponding to an integrated system to be analyzed, to classify data items constituting the database as “individual data” or “common data.” At this time, the system building assisting apparatus desirably uses a capability corresponding to an access source indicated by the access history to classify each of the data items as “individual data” or “common data.

Abstract: Spherical particles having curvatures larger than those of irregularities, crystal grain boundaries, lattice defects or the like (referred to collectively as irregularities, hereinafter) on the surface of a conductive metal material are ejected at high speeds to make the particles collide against the surface of the conductive metal material, thereby repeatedly causing rapid melting and cooling at the minute points of impact of the particles, thereby changing the surface into amorphous. Then, spherical particles having curvatures smaller than those of irregularities on the surface subjected to the treatment described above collide against the surface, thereby changing the surface into amorphous and planarizing the surface.
