The Study And Realization Of Distributed Computing Of Comprehensive Information Service System For Self-study Examination

With the rapid development of information society and knowledge economy, education informationization has become the development demand and inevitable trend. Meanwhile, with the emergence of open education, like E-learning University, kinds of advanced education bring Self-study Examination Education into competition. At present, there are lots of service systems for Self-study Examination, but they exists independently as themselves and it is difficult for them to exchange or share data, which results in detached island of information, and then delay the development of the informationization of advanced education. The problem is proposed: how to develop and use internet information resource efficiently and build the comprehensive information service system for Self-study Examination, organize and manage distributed and heterogeneous information resource of Self-study Examination, implement the interoperation of different management information system in order to improve management level and service quality and provide better service for the students of Self-study Examination has become the focus of the informationization development of Self-study Examination.The traits of information resource about Self-study Examination such as distributing, heterogeneity and local convergence determine that only if distributed computing is adopted, we can make the implementation of interoperation and interconnection of comprehensive information service system for Self-study Examination. The paper based on the comprehensive information service system for Chongqing Self-study Examination, analyses the traits of Web Services technique, makes deep research in kinds of distributing solution, proposes one distributed solution for comprehensive information service system for Self-study Examination and designs, implements the comprehensive information service system for Chongqing Self-study Examination. In one word, the paper does some research as follows:The current situation and the main problems of distributed computing techniques and education informationization are analyzed and summarized. The situation of distributed computing applied to education informationization is discussed too.Three types of current mainstream techniques of distributed component object implementation and their existed problems are analyzed, several kinds of common...
