This paper presents the communication protocol between applications and remote databases in enterprise systems. Although the International Standard OSI-RDA has presupposed of the 1 request - 1 response communication protocol for the remote database access, it is not suitable from the view of system resources occupation and communication overhead in the case that the system should handle the large volumes of multimedia data. This paper proposes a server driven communication protocol in order to solve these problems, and compares the traditional method and the proposed method on the followings: (1) the number of communications, (2) the number of the encoding-decoding, and (3) the dynamic steps. According to the quantitative comparison, the proposed method makes the effort of avoiding communication resources occupation and improves 50% of communication overhead in case of only a large communication data. This paper also implies the guideline for suitable number of data segmentations for the remote database access.
