Stage Development Model of Digital Valley Based on Subject-point-source Database

Aiming at valley data's feature such as multi source, multi dimension, multi type, multi variant, multi volume, multi subject, this paper uses the design thought of "subject point source database", which can meet the fusing management of valley data in great quantity, to build digital valley engineering. Based on "Subject point source database" system,"Multi S" integrating stage development model of "digital vally" is established.
