Soap Protocol In Electronic Medical Records System

With the popularization of the Internet technology, the Electronic Patient Record (EPR) system is not only provided with function about rapid data_entry but also at present time provided with data_traffic by Internet to strengthen medical cooperation and to offer remote medical service. Before such circumstances, as a sort of communication protocols, SOAP can be used from data traffic to RPC (Remote Process Call) , it usually takes HTTP(which commonly firewalls don' t forbid) as transport protocol, so SOAP afford an approach for communications through firewalls and interoperability among different struction platforms;Applying SOAP to EPR system can solve the problems of the interoperability, data communications through firewalls and sharing information of the EPR system. A distributed EPR system was developed based on SOAP transport protocol by us, in combination with Web Service technology.At first the thesis introduces Web Service teconology, Web Service technology are certain technology, correlative agreements and much standard and so on, which can to describe, to publish, to searches and to call Web service in Internet. The Web Service tenology consists of XML, SOAP, WSDL and WSML and so on which are used to design and to implement EPR system, for instance, SOAP messages are all XML decument; used to communicate information between system client point and server point is the SOAP protocol; WSDL and WSML technology of the Web Service are both applied in designing and implementing the SOAP server, the WSDL describes Web service to provide to client, and WSML maps the RPC to current COM call . Then the thesis discusses in detail SOAP protocol message frame structure, and studies message mechnism between system client and system server, for example, to send SOAP requests, to receive and to deal with SOAP request, to build SOAP response and to deal with SOAP response by client. On the basis of discussion above, the thesis puts forward a EPR system model and implementation scheme of the EPR system based on SOAP-SOAPEPR, and discusses design and implementation of the system, studies intensively some sixty-four-dollar questions the system faces, which are: to analysis and design system, to implement system , including how to implement system server, system client and to enture system security,etc.Experimental results show that, technical scheme designed is advanced and applicable, and system implemented is basically practical too.
