The research on the query optimization strategy of the VDSI system database

As a large information services system based on RFID (Radio Frequency Identification) technology, VDSI (Vehicle Digital Standard Info-source) system needs to deal with a huge number of data everyday. As a result, the query speed is one of the most important facts in the design process. The paper introduces a means that optimize the database by means of indices, which can indirectly improve the efficiency and speed of database queries.
