<P>PROBLEM TO BE SOLVED: To provide a program for managing a tree structure, a tree structure management method, and a tree structure management device that share a production rule for producing the tree structure and can easily utilize a common tree structure. <P>SOLUTION: A production rule creating section 16 of a user side terminal 10 creates a production rule for producing the tree structure of an object based on data inputted by a user. A production rule storage section 22 of a management server 12 receives the production rule created by the production rule creating section 16 via the network 14, and stores it. Using a retrieving section 24 of the management server 12, the user retrieves a desired production rule from the production rule storage section 22 based on an command from the user side terminal 10, and transmits it to the user side terminal 10 via the network 14. A decrypting section 18 of the user side terminal 10 decrypts the production rule retrieved with the retrieving section 24, and produces the tree structure of the object based on the production rule. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
