Study Of Universal Item Bank System Based On XML

With the development of computer and network technology, item Bank System is becoming a new discussion in recent years. It can reduce the burden on teachers greatly and improve work efficiency, and increase the reliability of the examination. A great variety of Item Bank System is improving constantly that is developing from localized to the overall development and from concentration to distribution. When many information management systems upgrade continually, data sharing and communication become a new hotspot.Data exchange system is becoming the basis of the exchange of information between system and system. The thesis shows some problems when Item Bank System is developing, then discusses necessity and significance of Item Bank System.The various types of application systems with the development of computer technology has been gradually upgraded. One school may have several Item Bank Systems, but the databases of these systems are not idential, so the heterogeneous databases system is formed. If we implement access and communication in these systems, the data exchange in heterogeneous database is the foundation for unifying school information and implementing effective management. Based on the analysis of the primary characteristics of XML, Web Service and MathML have some advantages in Item Bank System that are the application of XML. The thesis come up with a highly versatile XML-based data exchange model by analyzing the basic content and the core elements of data exchange that is extensible. The data exchange model is for the flexibility, reusability and a high degree of scalability as the main design goals. It can be used as the data exchange system development model and the guidance of the basic principles.The thesis takes the ShenZhen Electronic Technical School Universal Item Bank System as background. It takes Data sharing and function sharing as the main goal. It also discusses Item design and implementation in use of ths popular ASP.NET technology and SQL SERVER database, and implement the data sharing between system and system by using data exchange model.
