The Research Of The Remote Teleducation Platform For Par Method Based On Web Service

Under the subsidy of multiple national-level subjects, Professor XueJinYun Have put forward a formalized method that can designed and proved creativly a simple and practical algorithm, it called par method, This method includes algorithms and designs language Radl, abstract programming language Apla language and automatic converting system of relevant procedures. His two key technology Can replace at present using generally divide and rule law , dynamic planning law, greedy law ,etc. algorithm design methodFirst, the teacher can't get it in time , effectively teaching quality is feedbacked, can't give full play to the extention and universality of network distance learning . Second , can't use the advantage of network distance learning to carry on individualized education to students' one's own characteristic , still repeat old electricity type education. Third, because the privacy of PAR method platform and limited bandwidth of network, can't let students carry on practice to knowledge in the teleeducation platformAnd Web Service technology which a new generation develop plays an important role to the development of Internet at present, it has defined the application program interface how the application program realizes operating each other on WEB, because of the above understanding, we are expanding on the foundation of Web Service, and propose on this basis the teleeducation that one group is correlated with defines the interface, and to the problem of solving First part Introducing the brief one to PAR method, including PAR method course, expresses symbols, generally acknowledged truth system ,etc. second part Introduce Web Service agreement. It includes the following several someXML: Is it let different to construct platform communicate and share datum each other with the system to want, the data then transmitted on WEB must appear with certain standard XML form. SOAP: It is a kind of interchangeable one, because of XML standard, visit the agreement among the targets of the text, it ask and is it bale visit of target into XML file to respond, transmit among the targets.WSDL: Namely WEB serves the language of describing, can let other systems know WEB SERVICE has offered those services.The third part Realize some. The ones that provided the key technology of platform each module and meritted attention took some difficult points , and need the place of improvement relevantly. Provide the main technical indicator that the application program of this text realizes at the end of the article, and the place to need to perfect further.
