Real-Time Query Method Based on Distributed Database Demand Information

This paper proposes a real-time query method for distributed database requirement information. First, we propose to extract the information according submitted keyword. Then, establish model of demand and classification model, using multivariate hash algorithm When there is keyword, proposed directly reads data above ring based on keyword improve efficiency. Extensive experimental results indicate that our reduces number queries, pressure, processing time queries in database. Moreover, database’s rate amount have increased.
