- Data processing method in In-memory Database System based on Circle-Queue

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a database system, and more particularly, to a system and method for improving storage efficiency in an in-memory database system by storing data continuously changing, such as moving object position data, To a method of processing data in an annular queue based in-memory database system.The method of processing data in an annular queue based in-memory database system according to the present invention is characterized in that the database management apparatus stores time-space-related data continuously input from the outside in a memory page of a memory database, A second step of monitoring whether or not there is a data record satisfying predetermined aging-out conditions by monitoring the memory database in the database management apparatus; If there is a data record satisfying the aging-out condition in the second step, the database management apparatus searches for the aging-out target data whose storage time exceeds a predetermined time in the data record, A fourth step of reading out and deleting the aging-out object data retrieved in the third step from the corresponding data record or backing-up the data in the external storage means; and the database management device stores the input space-And storing the data in an aging-out object data storage area.;
