The present invention relates to a circular queue-based in-memory database system and a data processing method of same, the circular queue-based in-memory database system comprising: a memory database having a plurality of circular queue-based memory pages for storing data; and an external storage means for backup storing data to be aged out in the memory database. According to the present invention, data is stored in the memory pages of the memory database. The memory pages stored in the memory database are monitored and, with respect to a memory page that satisfies an aging out condition, data to be aged out which exceeds a fixed storage time is deleted or stored in the external storage means, and then data being input thereafter is stored in a data-to-be-aged-out storage area in the memory page. |
