This paper concentrates on reducing the cost of I/O and improving algorithm efficiency by designing and realizing a spatialdataaccess system based on main memory database (MMDB). We use Redis to manage vectorspatialdata in main memory which is faster than hard disk or disk-based database in respect of dataaccess. We design a management strategy of spatialdata, internal and external data exchange strategy and data backup mechanism. Based on MMDB, we design the model of vectorspatialdata to describe its form, organization and access methods. The experimental results show that our dataaccess strategy can cut down the time of I/O and improve the algorithm efficiency effectively.
