Abstract: The Ministry of Land and Resources needs to provide administration data to provincial departments according to administrative division code in order to improve provincial information level.This paper designs and realizes a mining administration data service system(MADSS) based on ESB and SOA. Firstly, it describes the MADSS’s requirements analysis, outline design, architecture design and function design. Secondly, it describes some core processes of MADSS, such as data service development based on SOA and data mapping templates, data service registration based on ESB, data service calling based on service broker. At last, it introduces the actual operation of six kinds of mining administration data service instances, for example mining rights data service, which are already running online. The MADSS provides a new channel for data sharing between the Ministry and provincial departments, and develops a practical model of data sharing.
