Database access technology based on VB

Turn p. 79) 4 Zhang M et al: Remote Sensing Image Based on Oracle9i Database Technology Research and Implementation of 79DIB conducted consistent with the conventional approach, the treatment effect observed for not only the final result of the situation arising. 6 Design and Implementation of the prototype system during the experiment, the preparation of the Oracle9i database based prototype system for remote sensing image database, the remote sensing image data contains a large amount of data, and Oracle database management system itself larger memory requirements,[link widoczny dla zalogowanych], therefore,[link widoczny dla zalogowanych], the computer running the database server hardware requirements higher. Experimental test data used is about 20GB, the system test environment using a P42.0GCPU, 512G memory PC. Experiments show that Ora. cle9i remote sensing image database management system in the actual operation is feasible. References: [1] Ni Jinsheng, Li Qi, Cao Xuejun.
