At present, there are some problems in the existing information system of the survey and design enterprise such as inadequate planning, lack of normalization and standardization of system combination, etc. The SOA-based enterprise application integration allows information systems to achieve flexible business processes and meets demands in adapting to the changes quickly and other business development needs. This paper, based on the SOA framework, puts forward a solution aiming at the application integration of the survey and design field and builds up the ESB-based enterprise application integration framework. The ESB-based as well as SOA-based survey and design enterprises application integration framework enables to join the enterprise information system, business data and business process perfectly, to solve the problem of the “isolated-island” information system of the prospecting and design enterprise effectively, and to improve the efficiency and coordination of the enterprise.
