DATA STORAGE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a data storage system capable of reducing communication time and communication cost.

SOLUTION: The system comprises a temporary cache means 104 which temporarily stores data; a permanent cache means 105 which stores the data for a predetermined period; a cache selection means 106 which selects whether the data is to be stored in the temporary cache means 104 or the permanent cache means 105; and a data classification means 110 which classifies the data into temporary cache data and permanent cache data. Thereby, verifying and updating of the permanent cache data can be eliminated.
