The Development And Research Of Network Teaching System Based On XML

With the rapid development of Internet and constant improvement of various school information-based degree, the resource of online education get richer and richer, and Internet/intranet-based teaching way has already rooted in the hearts of the people, which promoting the process of our country's education reform and the change of the people's study idea. However the rapid development of the network makes the existing network technology face all sorts of challenges too, and there is no exception in network education. Therefore, people develop constantly new technology to satisfy the need of network development, XML has many characteristics such as facility, flexibility and powerful function and so on, which wins the favor from researcher and developer deeply. Structuring the network education system based on XML has already become an important developing trend in online education.The paper first introduces briefly network education system, enumerates out the meaning of structuring the network teaching system based on XML, and analyzes the current situation of domestic and abroad that XML technology applied to network teaching.After introducing necessarily some technologies related to network education system based on XML, in the third chapter, divides in detail to the overall function of the network tutoring system and introduces concretely it, and designs database on E-R model. The content of chapter 4 is the key point of the paper, which introduces in detail the lower-level implementation of several main functions of network education system. Include four following respects mainly: compound control of DataGrid (use package technology, design and implement compound control of DataGrid); the similarities and differences about the implementation of the mutual of lower-level datum of the test questions database management system (design and implement a mutual module of lower-level datum based on XML, and optimize further) ; using XMLHTTP and WEB SERVICE to implement the mutual platform without refresh (use the technology of XMLHTTP and WEB SERVICE to design and implement the mutual platform without refresh) ; answering system automatically (implement tentatively partial functions of answering system automatically and propose a intelligent expand module of the knowledge database).Finally, on the basis of summarizing the whole paper, prospect the research and development of network education system based XML technology.
