Research Of An Schoolwork Description Language Based On XML Schema

Research of an Schoolwork Description Language Based on XML Schema is a new realm in the educate inforation-based realm nowadays, especially in the fast development process of the network and long distance educate. Currently, the on-line schoolwork management system is the on-line teaching support system to lack the widespread present condition of correspond the norm in a count for much sub- system, not only result in the waste of a great deal of manpower, material resources, financial power and education the information resources, and the standard is different, repetition construction, share with operate with each other impediently , the guarantee mechanism that circulate and safety is not the dint, already certain a check and supervision of degree the quantity and the performance of the network teaching and network study. Research of an schoolwork description language based on XML Schema is a long-term, complexity, comprehensive and the high-technique system engineering,the content that it include and postpone to still lack outside to unify the define definitely.The research of this thesis is just the initial trial of a quest, the main research method adopt have: to study the standard of XML; to study the reference data;to study the norm, even design a description norm for correspond to concrete application with the XML; to make use of the norm to design relevant file;to create an instance on-line schoolwok system based on XML Schema.In the first part this paper depicted the writer's study cause and its object ,analyzed at home and abroad basic present condition, explained the research method of this thesis adoption on this foundation. And then in the second part of this thesis XML theories foundation I introduced the background that XML bear, described the XML characteristics, explained the XML marking, analyzed the XML basic structure, analyzed the DTD and XSD different and similars, enumerated XML main and applied realm. In the design and realizations of the third part,I analyzed the schoolwork data model, build up to framework of Schema, wrote related instance, Elaborated the verification, manifestation and saving of the XML text file.Afterwards in the forth part , I discussed particularly its three matters : the development characteristics, the development model, the design principle and needs of the system; The system structure and a function of mold; The system realization. In this part, I designed an Web schoolwork management system prototype according to XML Schema.The system around the XML launch, maked use of some techniques,such as JAVA, HTML, ASP etc., carried out the schoolwork born ,the operation of management course and student basic information. In this process,I showed completely how born data of XML, how withdraw the data of XML, how show the data of XML with accuracy, how the conservancy XML data according to the code of the system.In a word, this thesis is from its research meaning, theories foundation, main research contentsand instance etc., carried on the difficulties to its quest. The thesis elaborated the background of its ages and realistic significance, maked sure its research method. According to the characteristics and requests that schoolwork manage, constructed the data model tree of a schoolwork text file and an answer text file. At these two pieces according to the foundation of the model tree up, carried on the Schema mode design, made to this to further expand, and give complete definition of the model tree XSD.Finally, design an Web-based schoolwork management system based on the lauguage of XML Schema.
