Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying inheritance relations of hierarchical structure data, and in particular, a hierarchy for displaying the mutual relation of data of a hierarchical structure data group having multiple inheritance relations by a graphic showing the inheritance relations by lines. Regarding inheritance relation display method of structural data.

[0002]

2. Description of the Related Art Conventionally, in order to graphically display a mutual inheritance relationship of a data group having a hierarchical structure, as shown in FIG. 2, a line indicating the inheritance relationship of constituent elements (data names) arranged by hierarchy is shown. It is represented by drawing a dendrogram linked by.

The data group shown in FIG. 2 has 13 layers of 13 layers.
Each piece of data is included, and the data connected by a line indicates that the data in the lower layer is inherited from the data in the upper layer and has an inheritance relationship. In addition,
When certain data is inherited from a plurality of upper layer data, it is said to have multiple inheritance. In FIG. 2, the data 205, 206 and 209 are in a multiple inheritance relationship. Generally, when the amount of data that has undergone multiple inheritance increases, it is inevitable that the lines representing the inheritance relationship intersect and become difficult to understand.

In the conventional display method of the inheritance relationship diagram, the entire data representation is displayed on the screen and shown to the user as it is, or when the entire data representation is complicated and cannot be displayed on the screen, it is simply displayed. A part of FIG. 2 was cut out and displayed.

[0005]

In the above-described conventional inheritance relationship display method for hierarchical structure data, when the hierarchy and the number of data are large and the multiple inheritance relationships are complicated, the lines indicating the inheritance relationships on the screen intersect. Then, there is a drawback that the display is confused and it becomes difficult to understand.

An object of the present invention is to provide a method of displaying the inheritance relationship of hierarchical structure data in which only the inheritance relationship centered around the required data is extracted and displayed in an easy-to-understand manner.

[0007]

A method of displaying a inheritance relationship of hierarchical structure data according to the present invention includes a data storage unit storing information including an inheritance relationship between data in a hierarchical structure data group, and each data in the data storage unit. Is classified into top-level data that is not inherited from other data at all, multiple inheritance data that is inherited from multiple data, and single inheritance data that is inherited from only one data. Data analysis means to be created, selection switching means for displaying the classification table on the screen and instructing selection of the central data, and the top-level data, multiple inheritance data or inheritance centered on the data designated by the selection switching means And a display unit for displaying on the screen an inheritance relationship diagram of a range up to the lowest data without a destination.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

As shown in FIG. 1, the hierarchical structure data inheritance relationship display method of the present embodiment uses a data storage unit 14 storing information related to each other in a hierarchical structure data group and data in the data storage unit 14 at the maximum. Data analysis means 11 for creating a classification table classified into upper data, multiple inheritance data, and single inheritance data, and a selection switching means 12 for displaying the created classification table on a screen and instructing selection of central data. , And a display means 13 for displaying an inheritance relationship diagram centering on the data designated by the selection switching means 12 on the screen.

The data analysis means 11 includes a data storage unit 14
The data stored in is analyzed, focusing on the elements that have multiple inheritance relationships. First, the data storage unit 1
The data stored in 4 is taken out in order, and it is checked how many data it inherits. A classification table of the format shown in FIG. 4, which is classified as top-level data if it is not inherited from anywhere, multiple inheritance data if it is associated with two or more upper layer data, and single inheritance data if there is only one. Register in each column. At this time, it is recorded based on the data in the data storage unit 14 which data each registered data is inherited from and which data is the inheritance destination.

The selection switching means 12 is a data analysis means 11
The classification table obtained by the above is displayed on the screen, and when the user selects and instructs the data to be displayed from the displayed classification table, the information is transmitted to the display means 13.

When the display means 13 receives the data name to be displayed from the selection switching means 12, the data analysis means receives information such as whether or not the data has undergone multiple inheritance and which data is the inheritance source and the inheritance destination. 11, the data storage unit 14 stores only the data having the inheritance relationship with the designated data within the range from the designated data to the highest data, the multiple inheritance data or the lowest data.
Take it out and display it on the screen.

That is, according to the method of the present invention, it is the same as the conventional method that the display is made by tracing the inheritance destination that inherits the data of interest and the inheritance source that has been inherited. Only the data that has been classified into the multiple inheritance data and the highest level data in 11 are displayed. As a result, as is clear from a display example described later, no line intersects the line connecting the inheritance relationships, so that the inheritance relationship can be grasped by concentrating on the data of interest.

As described above, the user can specify the necessary data while looking at the inheritance relationship classification table of the hierarchical structure data group and display the inheritance relationship diagram of the range influencing the data in an easy-to-read format. Become.

FIGS. 3A to 3C are explanatory views of display examples of the inheritance relationship diagram according to this embodiment, and FIG. 3A shows the selection switching means 12 for the data 205 in the hierarchical structure data group shown in FIG. When the data is selected by the user in (1), (b) and (c) show the display contents when the data 206 and 209 are selected by the user, respectively.

When the data analysis means 11 analyzes the hierarchical structure data group of FIG. 2 stored in the data storage unit 14,
The classification table shown in FIG. 4 is created. The selection switching means 12 shows the classification table to the user as it is, and causes the user to input which data should be displayed. This table is very useful information for users.

The display means 13 receives the information inputted from the selection switching means 12, and the inheritance destination is centered on the data.
The inheritance source is displayed. Then, when the data to be displayed is multiple inheritance data or the highest level data, or reaches the lowest level data with no inheritance destination, the display is terminated there.

FIG. 3A shows an example in which the data 205 is mainly displayed. In this case, the data 205 is the data 20.
It has a direct inheritance relationship with 1,202,203,210,
Since all of them satisfy the above-mentioned censoring conditions, no further display is performed, and as a result, the display shown in FIG.
It is displayed as shown in (a).

3B and 3C show data 20 respectively.
6 and 209 are display examples, and the case of FIG. 3B is the same as that of FIG. In the case of FIG. 3C, the data 204 and the data 206 only have a direct inheritance relationship with the data 209, but both the data 204 and the data 206 do not meet the above-mentioned termination condition, and therefore the data is further inherited. The data 201 and the data 208 are displayed by tracing the relationship.

As is clear from the above display example, since no line intersects the line connecting the inheritance relationships, it is possible to concentrate on the data of interest and grasp the inheritance relationship.

In FIG. 2, if there is an inheritance relationship between the data 204 and the data 210, the data 20
8-If the arrangement of the data 210 is not changed, the lines intersect as shown by the broken line in FIG. 5A, but if the arrangement order of the data in the hierarchy is changed, the data 210 and the data 209 are changed. The intersection can be eliminated as shown in FIG.

[0023]

As described above, according to the inheritance relationship display method of the hierarchical structure data of the present invention, the inheritance relationships of the hierarchical structure data are categorized and displayed so that the user can select the necessary data, and the multiple inheritance portion is displayed. By discontinuing it, the inheritance relationship is displayed in a way that is easy for the user to understand, which has the effect of facilitating data reference.
