Research And Implementation Of Grid-based Data Management System

Recently, Grid technology is a hotpot in computer field, the application research work on grid data management gets more attention from scientists. In field of electric system, data management system requests high performance in security,heterogenous,real-time,dynamic distribution and etc, and is in need of modifying original data management pattern, this problem can be resolved by data management technology under grid environment. Aiming at the application demand of electric system, the thesis analyses the data management technology of grid middleware Globus, proposes the main frame of Grid-based Data Management System (GDMS), emphasizes the design method and application technology of data interface module.The thesis analyses the main features of grid data management system, researches on data transfer, data replica, data access and integration technology in grid, analyses data replica model which is adaptive with electric system; proposes a solution of GDMS, research on the system's main frame,executing strategy and communication mechanism; puts the system into main function module, designs and realizes the data interface module: using database pooling technology to manage data connection, encapsules the heterogenous of end database.The thesis formulates the implementation technology of using GDMS in Shaoxin electric bureau; defines the system basic data table structure; aiming at whether to use memory database table, designs the data update speed test experiment. Result proves that GDMS is widely applicable the electric system of high request on data connection and data share.
