DATABASE IMPROVEMENT SYSTEM

摘要

An improved database system may include a root-server including a computer processor. The system may also include a segment-server including a computer processor, the segment-server to store data based upon the data's frequency of use by a client who is closer to the segment-server than the root-server and any other segment-server in the system, and the data stored is at least write data. The system may further include a consistency unit to update the root-server based upon data stored by the segment-server and client.
