Abstract
Cloud information tool becomes popular as an enterprise business application, so that the number of enterprises who use such easy tool has increased. On the other hand, it is difficult to develop an in-house production management system on Cloud, because such system needs to have high security protection. In this study, an application program interface to cooperate with in-house RDB is developed, which also connects to another API provided by well-known webserver system. As an experimental case study, the proposed system is implemented as an order management system in a small manufacturing enterprise (SME). The results show that the system effectively performs to share the estimation information of repair orders between sales parson and plant managers.
