Application Of Dsta Exchange Technology In Digital Campus

As one of major contents of China's educational informationization construction, college informationization has achieved great success after more than 10 years of hard work. The construction focus has gradually shifted from the initial campus network construction, which is mainly based on computer, network and hardware infrastructure, to digitized campus construction, which emphasizes teaching application, cooperation in research and development, resource sharing and E-school, etc. Especially, the successful application of some application software systems is exerting more and more influence in college in every respect, such as teaching, researching, management, even campus culture and campus life. With the increasing number of school application softwares, some problems, such as Information Island, inconsistent information, confusing data, become more serious. Based on mature application systems, integrating school information resources standardizely to form integrated and standard data information can resolve these problems. Through school data exchanging and sharing, standardize working procedures, and achieve promoting education informationization, scientification of decision-making, regularization of school management through management and procedure reconstruction, and then provide teachers and students with the information platform of teaching, studying and researching. Through data exchange, data in different application systems is integrated effectively, which eliminates Information Island totally, improves school management, increase work efficiency at different departments, and free teachers from miscellaneous work. Therefore, it is very significant to research the application of data exchange in digitized campus.This paper is based on the advanced technologies,idears such as EBS,SOA,J2EE and so forth,frame-supporting,lightweigt and general data exchange platform. To build a safe and reliable public data exchange system ,realize the dada exchange and the dada sharing among every application system; It mainly solves the problems as follows:To establish the united information standard which is the basic of the data exchange;To set up the united information gateway to put the management of information resources and application survices together,so that it can provide personalized composite information survices to the majority of teachers and students.To establish a united identity certification system ,put the management of users and unite permission together, ensure the uniqueness,truth and authority of users'electronic identity so that it can help users to login with single click and one-step survices.To build a safe and reliable public data exchange system, realize the data exchange and the data sharing among every application system.To realize the seamless access of all kinds of data source that in different structure in the school,set up a database which can reflect the teaching,research work of the school,the work,learning and life of the teachers and students comprehensively.The datas are not only required to be highly concentrated but also to be safe and reliable which will be used to provide shared data support for the construction of digital school.To set up the unique credible information source in the school,eliminate the phenomenon that due to the differences between the statistics of caliber and time.
