Description

  The present invention relates to a data management apparatus and a data management method.

  Conventionally, there is a mechanism for converting CAD data into digital mockup data whose data amount is reduced by performing polygon conversion or the like, and managing the converted digital mockup data. For example, a PDM (Product Data Management-Product Data Management) system, a PLM (Product Life Cycle Management) system, and the like are generally known.

  For example, the technology described in Patent Document 1 centrally manages files created using a word processor, CAD software, etc., and a DB (Data Base) such as a bill of materials, parts information, and problem management information. .

  There is also a display color management method in which conversion rules from component attributes constituting digital mockup data to display colors are defined in advance, and a user can select an attribute and perform color-coded display of components according to the rules (for example, , See Patent Document 2).
