Abstract
In order to reform the shortcomings of common database with a slower access speed and lower security level, this paper applied sector operating directly instead of general file access, and used the distributed computing and clustering techniques to form an information server cluster as the special database system. Firstly, the layout and sector segmentation methods were provided for data access in sector based database. And then some management methods were given to control information servers in the cluster. Finally, to more efficiently schedule the tasks for storing data and querying information, a dynamic and self-adaptive scheduling algorithm was introduced into the application server of cluster. The practice shows that the system developed by this design strategy has good efficiency and security, and the access speed of the special database system is almost 25 times than that of common database.
