A data management system comprises: an outsourcer terminal outsourcing a fabrication by an instruction document; an outsourcee terminal receiving outsourcing and/or sub-outsourcing; and a server device. The server device comprises: a data management unit managing a proprietary authority of data stored in a data storage unit; an order container storage unit storing an order container with which data stored in the data storage unit is correlated, for each order created in an order creation unit of the outsourcer terminal and/or the outsourcee terminal; and an order container management unit managing sharing of the order container, based on an instruction from an order container sharing authority management unit of the outsourcer terminal and/or the outsourcee terminal. The server device, for each order, correlates any format of data element stored with the order container, for management.

In a shade guide, a plurality of shade tabs whose colors are mutually different are arranged regularly based on the colors. The arrangement of the plurality of shade tabs is an arrangement determined based on: S values and V values that are determined according to to which areas, from among areas partitioned by a plurality of straight lines in an L*-C* plane, the coordinates of the colors of the shade tabs belong, and H values that are determined according to to which areas, from among areas partitioned by a plurality of straight lines in an a*-b* plane, the coordinates belong. S groups, each of which is a shade tab group having a common S value, are arranged in the shade guide. V rows, each of which is a shade tab group having a common V value, are arranged in each S group. In each V row, the plurality of shade tabs have mutually different H values and are aligned in an order that is in accordance with the H values. Using this shade guide enables precisely and easily discriminating the color of an evaluation target tooth.
