Browse and Query System of remote sensing satellite image data supplies query service for remote sensing satellite users to inquire and search raw data and each level product of satellite image.However,with more and more remote sensing data information in the database,when many user's query concurrently occurred,the system requires considerably longer time to response.Some optimization technologies were put in practice from database server,application server and application program,and tests proved efficiency of these optimized techniques.
