[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a display device, and more particularly to a display device that displays a plurality of items having a parent-child relationship with nodes and links.
[0002]
[Prior art]
Generally, regarding a large-scale system composed of a plurality of subsystems, various information and data are managed in accordance with the structure of the system. As an example of a large-scale system, when an organization such as a company is considered, the organization can be divided into multiple departments, and more than one section that constitutes each department, depending on geographical elements, differences in roles, target fields, etc. The members of the organization belong to these departments or divisions. Such an organizational structure has a hierarchical structure, and a relationship between items located at different levels, for example, a relationship between a department and a section, and a relationship between a section and a person can be considered as a subordinate relationship or a parent-child relationship.
[0003]
Similarly, organizational activities can be hierarchized, and so-called parent-child relationships can be found among items belonging to each hierarchy. For example, when the organization manufactures a plurality of products, there is a manufacturing process or work process for each product, and at least one operation exists in each process constituting one manufacturing process or work process. As described above, there are hierarchical levels of products, processes, operations, etc. in the activities of the organization, and a parent-child relationship exists between items (products and processes, processes and operations) belonging to each hierarchy. In addition, there is another dependency or parent-child relationship in the process, which is an order between a plurality of operations in time series.
[0004]
Conventionally, in order to manage information related to systems such as organizations and work processes as described above in a database, items such as departments, sections, people, processes, operations, etc. constituting the system are dependent on these items. Or it is recorded with information about parent-child relationships. In such a database, each item described above is “data” recorded in the database, and at the same time, if the item is a “parent” having a “child”, the item that is the “parent” is “child”. ", That is," data group "having data.
[0005]
Furthermore, when using the information recorded and managed in this way, the display device has a system structure, that is, a tree comprising a plurality of items and a parent-child relationship between these items, and links connecting the nodes. Expression and display are performed according to the structure (see, for example, Patent Document 1). In this way, by displaying the system structure by the tree structure, the target data can be easily identified.
The applicant has not yet found prior art documents related to the present invention by the time of filing other than the prior art documents specified by the prior art document information described in this specification.

[Problems to be solved by the invention]
However, one matter (element) constituting the system is subordinate to two or more other matters, such as when one person belongs to a plurality of departments in an actual company organization or concurrently serves as a business. In this case, the system cannot be displayed in a tree structure whose parent is one element. For this reason, when an organization as shown in FIG. 3 is displayed in a tree structure, it is necessary to display as many nodes indicating the items subordinate to a plurality of other items (parents) as many as the number of parents (FIG. 3). 13). As a result, there is a problem that one item is displayed in duplicate.
[0008]
On the other hand, if the relationship between the elements is displayed in a network structure, duplicate display of items can be avoided (see FIG. 14). However, due to the nature of the network diagram, each item cannot be arranged hierarchically and expressed, and there is a problem that it is difficult to intuitively understand the parent-child relationship between items.
The present invention has been made to solve such a problem, and provides a display device that displays each parent-child relationship intuitively and easily without duplicating each item having a parent-child relationship including a network structure. The purpose is to provide.
[0009]
[Means for Solving the Problems]
  In order to solve the above problems, the present invention provides:Parent-child relationship between multiple dataIn a display device that displays nodes and links,When an overall view showing all data with children as nodes is displayed,Means for selecting an arbitrary node;When a node is selected in the overall view, the mode shifts from the overall view display mode to the partial view display mode,With the selected nodethisDisplay a partial view consisting of nodes that have descendant relationships starting from the selected node and links that represent these node relationshipsWhen an arbitrary node is selected in this partial diagram, among the data that is a child of the selected node, data having no child is set as a new node, and this new node is defined in the partial diagram. Displayed in the partial view with a link indicating the relationship with the node selected inThe display means is provided. As a result, when an arbitrary node (item) is selected, the display device displays the node having a descendant relationship and the relationship between them as a partial view, starting from the selected node (item). The Therefore, if a node having a plurality of parents is selected, the relationship with the plurality of parents is not displayed in the partial view.

[0015]
The management server 1 has hardware including a server main body 1a which is a computer having a network connection function, a storage device 1b composed of a non-volatile storage medium such as a hard disk storing a database, a keyboard 1c and a display 1d. The functions described above are realized by the cooperation of these hardware resources and a computer program that causes the computer to function as the management server 1.
[0016]
For example, the server body 1a is provided with a CD-ROM drive, and a computer program that causes the computer to function as the management server 1 is read from the CD-ROM and installed in a memory (not shown) of the server body 1a. The function as the management server 1 is realized by executing this program by the CPU (not shown) of the server main body 1a. The management server 1 functions as a display device according to the present embodiment by a computer program that causes a computer to function as the management server 1.
[0017]
Next, the management server 1 as a display device will be described with reference to FIG. FIG. 2 is a block diagram illustrating a functional configuration of the management server 1 as the display device 10. In FIG. 2, the management server 1 includes a Web server unit 11, a display control unit 12, a user information database (hereinafter referred to as user information DB) 21, and a work item database (hereinafter referred to as work item DB) 22.
[0018]
Here, the Web server unit 11 has a communication function based on the Internet protocol (IP), and displays a Web page generated by the display control unit 12 described later on the Web browser of the mobile terminal 2 and the terminal device 3. In addition, commands and data input by the operator on the Web pages displayed on the Web browsers of the mobile terminal 2 and the terminal device 3 are received and input to the display control unit 12.
[0019]
The display control unit 12 generates a Web page corresponding to the command or data input from the Web server unit 11 and inputs the Web page to the Web server unit 11. The Web page generated by the display control unit 12 includes an organization to which a plurality of users belong and a plurality of work items created based on information stored in a user information DB 21 and a work item DB 22 described later. A configuration diagram in which work processes are represented by nodes and links is included. In the present embodiment, the display control unit 12 can generate an overall diagram display page, a partial diagram display page, and an all data display page, which will be described later.
[0020]
The user information DB 21 and the work item DB 22 are databases constructed in the storage device 1b. The user information DB 21 records information on an organization, that is, information on departments, sections, and the like, and information on workers belonging to the organization, together with the dependency of these items (parts, sections, workers). . These items can be hierarchized according to their subordinate relationships, and the upper one is the parent (main) and the lower one is the child (secondary). Each item is data recorded in the user information DB 21 and at the same time can be considered as a “data group” composed of at least one item (data) subordinate to the item in the organization.
[0021]
In this case, the information regarding the organization is, for example, an organization name, an organization code, or the like. The worker information includes, for example, a name, an identifier for identifying the worker (worker ID), an authentication password, an affiliation, a work in charge, and the like. Hereinafter, the information related to the organization and the worker information are collectively referred to as user information. Here, “affiliation” is information indicating an organization which is a parent for the worker. Information indicating the parent-child relationship is called a “link”.
[0022]
The work item DB 22 records information related to product manufacture, that is, information related to the product, information related to the manufacturing process, and information related to the work item, together with the dependency of these items (product and process, process and work). These items can also be hierarchized according to their subordinate relationships, and the upper one is the parent (main) and the lower one is the child (secondary). In general, each process is composed of subdivided small processes, and some processes performed in each process and small processes are performed in other processes and small processes as well. . For this reason, the dependency which arises between a process and a small process or between a small process and an operation | work may become a network structure.
[0023]
In addition, there are work that can be performed simultaneously and work that is performed in cascade, and a subordinate relationship that indicates the order between a plurality of work in time series also occurs. For this reason, the work item DB 22 also records a subordinate relationship indicating the order among a plurality of works in time series. These items can also be hierarchized according to their subordinate relationships, and the upper one is the parent (main) and the lower one is the child (secondary). Each item recorded in the work item DB 22 is data recorded in the work item DB 22 and, at the same time, a “data group” including at least one item (data) subordinate to the item in the manufacturing process of the product. Can think.
[0024]
In this case, the information regarding the product is, for example, a product name, a product code, or the like. The information related to the product production process includes, for example, a process name and a process code. The information on the work item includes, for example, a work name, a number for identifying the work item (work number), work contents, and a process of performing the work. Hereinafter, information on products, information on production processes, and information on work items are collectively referred to as work item information. The user information DB 21 and the work item DB 22 are the same except that the type of data to be recorded is different.
[0025]
[Parent-child relationship of information]
Here, the parent-child relationship of information recorded in the database will be described using the user information DB 21 as an example. The matter recorded in the user information DB 21 is that when a certain worker belongs to two or more sections, the organization configuration, that is, the relationship between the items has a network structure. In this case, it is assumed that, for example, items having a parent-child relationship including a network structure as shown in FIG. 3 are recorded in the user information DB 21. In FIG. 3, groups A to F indicate organizational hierarchies such as departments, sections, and staffs, and are defined as data having children. Users 1 to 5 indicate workers belonging to these organizations and are defined as data having no children.
[0026]
In this case, in the user information DB 21, data of groups A to F, data of users 1 to 5, and links representing parent-child relationships between the data are recorded, and group A stores group C and group D as data. Data group, group B is a data group having group D and group E as data, group C is a data group having user 1 and user 2 as data, and group D has user 2 and user 4 as data. Data group, group E acts as a data group having user 3, user 4 and group F as data, and group F acts as a data group having user 5 as data.
[0027]
Next, the display device 10 according to the present embodiment will be described with reference to FIGS. The display device 10 has an overall view display mode for displaying an overall view display page, a partial view display mode for displaying a partial view display page, and an all data display mode for displaying an all data display page, and searches the user information DB 21. As a result, the entire organization, a part of the organization, and the entire organization including the members can be displayed on the Web browser of the terminal device 3.
[0028]
The overall view display page is a web page including an overall view that displays all data having children recorded in the user information DB 21 as nodes and displays links indicating parent-child relationships between these nodes. The partial diagram display page is a Web page including a partial diagram that displays a node selected on the overall diagram display page, a node having a descendant relationship starting from the selected node, and a link representing the relationship between these nodes. . The all data display page is a web page including an all data display screen that displays all data recorded in the user information DB 21 as nodes and displays a link indicating a parent-child relationship between these nodes.
[0029]
[Overview display processing]
First, an overall diagram display process for displaying the entire organization will be described. When an overall diagram display request for displaying the entire diagram display page of the user information DB 21 is transmitted from the terminal device 3 to the display device 10, the Web server unit 11 receives the entire diagram display request in the display device 10, and the display control unit 12 is input. The display control unit 12 shifts to the whole figure display mode in response to the whole figure display request, and executes the whole figure display process. Here, with reference to FIG. 5, the operation of the overall diagram display process will be described. FIG. 5 is a flowchart showing the operation of the overall diagram display process.
[0030]
The display control unit 12 transmits a command for retrieving the user information recorded in the user information DB 21 and its link (step S01). The user information DB 21 that has received an inquiry by this command transmits all the recorded user information and its links to the display control unit 12. When the display control unit 12 receives the user information transmitted from the user information DB 21 and its link, the display control unit 12 selects user information having a child based on the transmitted user information and the link, that is, information related to the organization, as a node. Set (step S02). In step S02, the information about the organization and the information about the worker are distinguished from each other in the user information in order to generate an overall view displaying only the organization. In the present embodiment, in order to create an overall view in which only the organization is displayed, the user information related to the organization has one or more children, whereas the worker is located at the end of the organization. The user information shown uses the property of having no children.
[0031]
After the node setting, the display control unit 12 recursively searches for the node from the root node and determines the display position (step S03). After the display position is determined, the display control unit 12 performs a drawing process of the nodes and the related links and generates an overall diagram that becomes an organization chart (step S04). The generated overall view is incorporated into the overall view display page together with related display data, and then transmitted to the terminal device 3 by the Web server unit 11, and the Web browser of the terminal device 3 displays the overall view display page.
[0032]
Here, one display example of the whole view display page is shown in FIG. This overall view screen has display areas of an information name display unit 61, a display mode selection unit 62, a selected node display unit 63, and a node display unit 64. The information name display unit 61 displays the name of the data to be displayed, and the display mode selection unit 62 displays selectable display modes. The selected node display unit 63 displays the name of the selected node, and the node display unit 64 displays the node and the link between the nodes and the node name showing the overall view.
[0033]
In FIG. 6, “user information” that is data to be displayed is displayed on the information name display unit 61, and the entire data display mode for displaying all data as nodes can be selected on the display mode selection unit 62. “All data” is displayed with a right-pointing arrow. In this case, by clicking (selecting / executing) the display mode selection unit 62 on the screen, the display mode can be shifted to the all data display mode described later. The selected node display unit 63 displays an “overall view” indicating an entire view display page. When the selected node display unit 63 is “overall view”, the node is not selected.
[0034]
The node display unit 64 displays all data having children as nodes, and displays a link indicating a parent-child relationship between these nodes. Here, the data having a child indicates a subordinate organization or an organization having a worker to which it belongs. In this case, nodes indicating data having children are displayed as circles, and links are displayed as arrows. In the following, circles indicate data having children, that is, an organization having a subordinate organization or a worker to which it belongs. In the vicinity of the circle, the name of the data set for the node is displayed as the node name. As for the arrow, the start point side is connected to the parent node, and the end point side (direction indicated by the arrow) is connected to the child node. Since the node display unit 64 functions as a so-called clickable map, when a node displayed in the node display unit 64 is clicked, a screen associated with the clicked node is displayed.
[0035]
[Partial view display processing]
Next, a partial diagram display process for displaying a part of an organization will be described. After the general map display page is displayed, when an operator selects an arbitrary node by clicking a node displayed in the node display unit 64 of the general map display page, the selected node is displayed by the Web browser of the terminal device 3. Are added to the partial view display request and transmitted to the display device 10. The partial view display request transmitted from the terminal device 3 is received by the Web server unit 11 and input to the display control unit 12 in the display device 10. The display control unit 12 shifts to a partial diagram display mode in response to a partial diagram display request, and executes a partial diagram display process for displaying a partial diagram starting from the selected node.
[0036]
Here, the operation of the partial view display process will be described with reference to FIG. FIG. 7 is a flowchart showing the operation of the partial view display process. In the partial diagram display process, the display control unit 12 sets the selected node ID added to the partial diagram display request as the starting node (step S11). Next, the display control unit 12 transmits, to the user information DB 21, a command for retrieving user information below the starting node and its link (step S <b> 12). The user information DB 21 that has received the inquiry by this command transmits the user information below the recorded origin node and its link to the display control unit 12.
[0037]
When the display control unit 12 receives the user information transmitted from the user information DB 21 and its link, the display control unit 12 obtains data having a child and data that is a child of the selected node based on the transmitted user information and the link. Select and set to node (step S13). In this case, the data having a child indicates a subordinate organization or an organization having a worker who belongs, and the data that is a child of the selected node indicates a worker who belongs to the organization designated by the selected node. After the node setting, the display control unit 12 recursively searches for the node from the root node and determines the display position (step S14). After determining the display position, the display control unit 12 performs drawing processing of the node and the related link, and generates a partial diagram showing the organization below the starting node (step S15).
[0038]
The generated partial diagram is incorporated in the partial diagram display page together with the related display data, and then transmitted to the terminal device 3 by the Web server unit 11, and the Web browser of the terminal device 3 displays the partial diagram display page. Thereby, in the partial diagram display page, the user information set as the starting node and the user information associated as its descendants, the user information having children, that is, the lower organization or the organization having the worker belonging to, User information that is a child of the selected node, that is, a worker belonging to the organization designated as the selected node is displayed as a node. In addition, a link having a node located on the parent side of the origin node and its descendants as parents is not displayed.
[0039]
Hereinafter, a display example of the partial view display page will be described. FIG. 8 is an explanatory diagram showing a partial diagram display page when a group B node is selected from the overall diagram display page shown in FIG. In this case, the group B node is set as the selection node and the starting node. This partial diagram display page has display areas of an information name display unit 61, a display mode selection unit 62, a selected node display unit 63, and a node display unit 64 similar to the overall diagram display page shown in FIG.
[0040]
In FIG. 8, “user information” that is data to be displayed is displayed on the information name display unit 61, and “partial view” is displayed with a left-pointing arrow on the display mode selection unit 62. In this case, by clicking (selecting / executing) the display mode selection unit 62 on the screen, the display mode is shifted to the above-described overall view display mode, and the entire page is displayed from the partial view display page. It is possible to make transition to the whole page display page.
[0041]
The selected node display unit 63 displays “Group B”, which is the name of the selected node. The node display unit 64 indicates a node having a child, that is, a subordinate organization or an organization having a worker belonging thereto by a circle, and a node having no child, that is, a worker belonging to a parent organization is indicated by a triangle. Show. In addition, links between nodes are indicated by arrows. An arrow has a parent node as a start point and a child node as an end point (direction indicated by the arrow). In this case, the node display unit 64 displays the group B set as the starting node and the group D, the group E, and the group F having descendants with a circle indicating that the node has children. Yes. Also, arrows indicating links between nodes are displayed between the circles. On the partial view display page, workers belonging to the organization designated as the selected node are also displayed as triangle nodes in addition to the nodes having children, but group B does not have any workers, so group B A triangle mark and a link indicating the worker to which the user belongs are not displayed.
[0042]
Next, after displaying the partial diagram display page, when the operator selects an arbitrary node by clicking the node displayed in the node display section 64 of the partial diagram display page, the selection is made by the Web browser of the terminal device 3. The selected node ID indicating the selected node is added to the partial view display request and transmitted to the display device 10. The partial view display request transmitted from the terminal device 3 is received by the Web server unit 11 and input to the display control unit 12 in the display device 10. In this case, since the starting node has already been set, the display control unit 12 regenerates the partial diagram below the starting node by executing the partial diagram display processing described in FIG. To do. The regenerated partial diagram is incorporated into the partial diagram display page together with the related display data, and then transmitted to the terminal device 3 by the Web server unit 11, and the Web browser of the terminal device 3 redisplays the partial diagram display page. .
[0043]
FIG. 9 is an explanatory diagram showing a partial diagram display page redisplayed when a group D node is selected from the partial diagram display page shown in FIG. In this case, since the group B node has already been set as the starting node, the group D node is set only as the selected node. In FIG. 9, “user information” that is data to be displayed is displayed on the information name display unit 61, and “overall view” is displayed with a left-pointing arrow on the display mode selection unit 62. In this case, as described with reference to FIG. 8, by clicking the display mode selection unit 62 on the screen, the display mode is shifted to the above-described overall view display mode, and the display screen is displayed from the partial view screen to the overall view. You can make a transition to the overall view screen.
[0044]
The selected node display unit 63 displays “Group D” which is the name of the selected node. In the node display portion 64, the group B set as the starting node and the groups D, E, and F that have children as their descendants are displayed together with a circle indicating that they are nodes having children. Is displayed with an arrow indicating a link between nodes. Furthermore, “User 2” and “User 4”, which are children of the group D that is the selected node, are displayed with triangles indicating that the nodes have no children, together with an arrow indicating a link from the group D. . Here, the circle of group D and the arrow indicating the link from group D are displayed in a different color from other nodes and arrows so that group D can be recognized at a glance. .
[0045]
Similarly, the case where the group E node is selected from the partial view shown in FIG. 8 or FIG. 9 will be described. FIG. 10 is an explanatory diagram showing a partial diagram display page redisplayed when a group E node is selected from the partial diagram display page shown in FIG. 8 or FIG. In this case, since the group B node has already been set as the starting node, the group E node is set only as the selected node. In FIG. 10, “user information” that is data to be displayed is displayed on the information name display unit 61, and “overall view” is displayed with a left-pointing arrow on the display mode selection unit 62. In this case, as described with reference to FIG. 8, by clicking the display mode selection unit 62 on the screen, the display mode is shifted to the above-described overall view display mode, and the Web page to be displayed is changed from the partial view display page to the entire view. It is possible to transition to an overall diagram display page that displays a diagram.
[0046]

Here, the circle of group E and the arrow indicating the link from group E are displayed in a different color from other nodes and arrows so that group E can be recognized at a glance. .
[0047]
[All data display processing]
Next, all data display processing for displaying the entire organization including the members will be described. When the operator clicks “all data” displayed in the display mode selection section 62 of the overall diagram display page during the overall diagram display page display, the web browser of the terminal device 3 issues an all data display request. Sent to. The all data display request transmitted from the terminal device 3 is received by the Web server unit 11 and input to the display control unit 12 in the display device 10. The display control unit 12 executes an all data display process in response to an all data display request. Here, the operation of the all data display process will be described with reference to FIG. FIG. 11 is a flowchart showing the operation of all data display processing.
[0048]
The display control unit 12 transmits a command for retrieving the user information recorded in the user information DB 21 and its link (step S21). The user information DB 21 that has received an inquiry by this command transmits all the recorded user information and its links to the display control unit 12. Upon receiving the user information transmitted from the user information DB 21 and its link, the display control unit 12 sets all the transmitted user information in the node (step S22).
[0049]
After the node setting, the display control unit 12 recursively searches for a node from the root node and determines the display position (step S23). After determining the display position, the display control unit 12 performs drawing processing of the nodes and the related links, and generates an all data display diagram that is an organization chart in which the members are displayed (step S24). The generated all-data display diagram is incorporated into the all-data display page together with the related display data, and then transmitted to the terminal device 3 by the Web server unit 11, and the Web browser of the terminal device 3 displays the all-data display page. .
[0050]
Here, one display example of the all data display page is shown in FIG. This all data display screen has the display area of the information name display part 61, the display mode selection part 62, the selection node display part 63, and the node display part 64 which are the same as the whole figure screen shown in FIG. In FIG. 12, “user information” that is data to be displayed is displayed on the information name display unit 61, and “overall view” is displayed with a left-pointing arrow on the display mode selection unit 62. In this case, as described with reference to FIG. 8, by clicking the display mode selection unit 62 on the screen, the display mode is shifted to the above-described general view display mode, and the display screen is changed from the entire data display page to the general view. It is possible to transition to the whole page display page to be displayed.
[0051]
The selected node display unit 63 displays “all data” indicating that it is an all data display page. When the selected node display unit 63 is “all data”, the node is not selected as in the case of the “overall view”. In the node display unit 64, all user information is displayed as nodes, and a link indicating a parent-child relationship between these nodes is displayed. In this case, the node indicating the user information having a child, that is, the organization having the subordinate organization or the worker who belongs is displayed with a circle, and the user information having no child, that is, the worker belonging to the parent organization is displayed. The indicated node is indicated by a triangle. Arrows indicating links between nodes are displayed between the circle marks and between the circle marks and the triangle marks. As for the arrow, the start point side is connected to the parent node, and the end point side (direction indicated by the arrow) is connected to the child node. The name of the data set in the node is displayed as a node name in the vicinity of the circle or triangle.

As described above, according to the display device 10 according to the present embodiment, each data having a parent-child relationship including the network structure of the data group recorded in the designated database is duplicated in the overall view display mode. It is possible to display an overall view that represents the entire related link. In this case, since only the data having children is displayed as nodes in the overall diagram, the entire parent-child relationship is easy to see.
[0053]
Furthermore, since the partial diagram display mode displays only the descendants of the node selected from the group of nodes displayed in the overall diagram as a partial diagram starting from the selected node, the parent-child relationship is displayed. Intuitive and easy to understand. Further, since the all data display mode is provided, it is possible to display the entire link indicating the parent-child relationship including the network structure without duplicating all the data recorded in the designated database.
[0054]
Here, the display of the data group (element) recorded in the user information DB 21 has been described as an example. However, the data group (element) recorded in the work item DB 22 can be displayed in the same manner. In addition, in the display of the data group (element) recorded in the work item DB 22, when there are a plurality of children subordinate to the same parent, the order between the plurality of operations along the time series is set between these children. When there is the dependency shown, the child with the earlier work order is displayed so as to be positioned on the upper side in the node display unit 64. The data that can be displayed is not limited to user information and work items. According to the display device 10 according to the present embodiment, all items of data having a parent-child relationship including the network structure are not duplicated. The parent-child relationship can be displayed intuitively and easily.

【The invention's effect】
As described above, the display device of the present invention includes means for selecting an arbitrary node, a node that is in a descendant relationship with the selected node as a starting point, and a link that represents the relationship between these nodes. Display means for displaying a partial diagram consisting of the items, so that only the descendants of the selected node are hierarchically arranged and displayed from the overall diagram that displays each item having a parent-child relationship including the network structure without duplication. be able to. For this reason, the parent-child relationship below the selected node is intuitively easy to understand.
[0056]
In addition, when an arbitrary node is selected in the partial view, the display means displays the data included in the element corresponding to the selected node as a new node that is a child of the selected node. Only the data that is the child of the selected node is displayed, and the data that is the child of the non-selected node is not displayed except for the element that is the node. For this reason, the number of links displayed between the nodes can be reduced, and the number of link display intersections on the screen can be reduced, thereby making it possible to display more easily.
[0057]
Further, the program of the present invention is a partial diagram comprising means for causing a computer to select an arbitrary node, a node having a relationship of descendants starting from the selected node and the selected node, and a link representing the relationship between these nodes. Therefore, it is possible to display only the descendants of the selected node in a hierarchical manner from the overall view that displays each item having a parent-child relationship including the network structure without duplication. Therefore, the computer can function as a display device that displays the parent-child relationship intuitively and easily without duplicating each item having the parent-child relationship including the network structure.
[0058]
This program also displays when a computer selects an arbitrary node in the partial view, and displays data contained in an element corresponding to the selected node as a new node that is a child of the selected node. Since it further functions as means, it is possible to make the computer function as a display device in which only data that is a child of the selected node is displayed and data that is a child of the non-selected node is not displayed except for the element that is the node. For this reason, the number of links displayed between the nodes can be reduced, and the number of link display intersections on the screen can be reduced, thereby making it possible to display more easily.
