Grid Database System Design And Applied Research

Along with the computer science and network technological development changing with each new day, as is big as the national strategic infrastructure, the geoscienee, and even to the universe infinite research, as slightly as enterprise's correlation management and individual study and the entertainment, does not have one not in the as far as possible use computer and the network resources, by realizes the work which the manpower is unable to complete. But grid starting, causes the people to be possible to regard and to solve the question from a higher level.The application and development of the grid technology will impel the promotion of the whole level of the global Intemet development. The grid database technique with the appearance of the grid provides a valid method of visiting and managing the database in the grid environment. But the interview and integration of the grid database plays a vital role in the grid database management system and becomes the hotspot in the grid technique research. Along with the OGSA norm unceasing development and the fusion with the existing WEB technique, the grid calculation technique is beginning to change over to the commercial application domain. Meanwhile the Globus Toolkit, the grid middleware tool bag, also obtains a further development. Unification inquiry language standard and norm facing the grid database visit and the integrated middleware are also unceasingly studying and in the formulation. Believed along with the grid technology gradual mature and the consummation, as well as the further mature of database visit and the integrated technology, the grid database visit and integrated middleware facing the multi- data pools, the network and the commercial use soon will be able to realize Therefore, the grid database visit and the integrated middleware by all means will develop and progress along with the grid technology.Combining the related technique of the grid and database, this text does the main work: Probed into the method and the technique of combining the JAVA and the XML document to analyze the XML text file on the foundation of the applied server TOMCAT and the grid tool GT3; Researched into the technique of the data exchange and data integration of the XML; Designed the conjunction buffer pool to the grid database interview and the integration, and the database conjunction pool is the module that is usually needed in compiling an applied service, for the service function too frequently connecting database is a bottleneck, and now we can remove this bottleneck by using the buffer pond technique; Made the research and analysis to the OGSA-DAI middleware, and through combining the XML technique, the database technique...etc, designed the new OGSA-DAI system structure and data integration module, constructed abstract virtual database service, in order to the integration and search of different structure database of the distribution type for the client.
