Embodiment Construction

[0061] Next, a tree structure data editing device according to the present invention will be described in detail with reference to the accompanying drawings.

[0062] FIG. 1 is a block diagram showing a functional structure of tree structure data editing according to an embodiment of the present invention. Referring to FIG. 1, the tree structure data editing apparatus is composed of databases 1 and 2, a differential tree structure data generating section 3, an output control section 5 and an output section 6.

[0063] Database 1 and database 2 respectively store first tree structure data and second tree structure data. The first tree-structured data and the second tree-structured data have some tree-structured nodes, and such nodes are constituted by unit data defining a hierarchical connection condition. The first tree structure data and the second tree structure data can be dynamically established in the database 1 and the database 2 . That is, each of the first tree struc...

Abstract

A tree structure data editing apparatus includes an output unit, a data base (1, 2), a differential tree structure data producing section (3) and an output control section (5). The data base stores first and second tree structure data respectively having first and second tree structures in which tree nodes are hierarchically provided. The differential tree structure data producing section compares the first and second tree structure data for every tree node, and produces a differential tree structure data hierarchically indicative of a difference between the first and second tree structure data in structure. The output control section analyzes the differential tree structure data, and controls the output unit to output a differential output between the first and second tree structure data based on the analyzing result.

Description

technical field [0001] The invention relates to a method for outputting differences between tree-structured data and a device for the method. Background technique [0002] In a known conventional tree-structured data editing device, data structure data stored in a memory is read out and displayed on a display unit. In such a conventional data editing apparatus, in response to a menu query, data in a tree structure is dynamically built to have a plurality of nodes from the highest tree structure in memory. In this unit data, a hierarchical link condition is defined. Tree-structured data built in memory is complex. Generally, a function is provided to output and display tree-structured data so that the user can recognize the creation status of the tree-structured data. [0003] However, there is no function provided to output a difference of two tree-structured data that a user can visually recognize. For this reason, the user must compare two tree-structured data and reco...
