Abstract:
To provide a memory database system or the like allowing high-speed development of table data onto a memory.
An operation server 10 develops contents of a file 31 onto a memory 14 as table data 15 as they are. The operation server 10 rewrites only a head address of each page in a page management table 151 to an actually allocated physical address. The operation server 10 transfers the table data 15 to a backup server 20. The backup server 20 deploys contents of the table data 15 onto a memory 24 as table data 25 as they are. The backup server 20 rewrites only a head address of each page in a page management table 251 to an actually allocated physical address.
