(2) Background and outline of the present invention The present invention relates to a usability degradation suppression function during system development in a low-code development tool.

In the midst of rapid changes in the business environment, it is essential that information systems keep pace with management speed, and speedy system changes are required. Under these circumstances, low-code development tools are attracting attention, and their user base is not limited to vendors, but is expanding to include system managers at companies using systems. Therefore, there is a demand for a mechanism that allows anyone to easily create a screen with high usability.

Here, in system development that does not use low-code development, in programming, if you want to implement processing, you can freely describe processing for each control event. As a result, there is a possibility that screen operations that the user cannot anticipate, such as "page transition" and "message box activation" due to check box switching, may occur during the verification process. There was also a problem with uniformity of behavior.

Also, in system development using low-code development, the same problem has occurred in the past, and it has been difficult to limit the actions that can be set for the events of each control.

Therefore, in the present embodiment, for example, by providing a check mechanism for actions that can be set for screen control events and controlling them, it is not appropriate to respond to screens with inconsistent behavior and user operations. Prevent screen development. In other words, in the present embodiment, for example, by defining each screen operation function (execution of business processing, screen transition, screen activation, etc.) for control events, Detect invalid settings. Specific configurations and operations will be described below.

The communication interface unit 104 has a function of communicating data with another device via a communication line. Here, the network 300 has a function of connecting the system development support apparatus 100 and the server 200 so that they can communicate with each other, and is, for example, the Internet or a LAN (Local Area Network). Data such as various masters described later may be stored in the server 200, for example.

An input device 112 and an output device 114 are connected to the input/output interface section 108 . The output device 114 can be a monitor (including a home television), a speaker, or a printer. The input device 112 can be a keyboard, a mouse, a microphone, or a monitor that realizes a pointing device function in cooperation with a mouse. Note that, hereinafter, the output device 114 may be referred to as the monitor 114 and the input device 112 may be referred to as the keyboard 112 or the mouse 112 .

The storage unit 106 stores various databases, tables, files, and the like. The storage unit 106 stores a computer program for performing various processes by giving commands to a CPU (Central Processing Unit) in cooperation with an OS (Operating System). As the storage unit 106, for example, memory devices such as RAM (Random Access Memory) and ROM (Read Only Memory), fixed disk devices such as hard disks, flexible disks, and optical disks can be used.

The storage unit 106 includes, for example, an action table 106a, a correspondence table 106b, control information 106c, logic flow information/action information 106d, and event information 106e.

According to the development support device 100 according to the present embodiment, in system development performed by a developer setting actions to be executed on a screen used by a user, inappropriate setting of the actions can be prevented. . The system development is preferably, for example, system development without writing any source code (so-called no-code development) or system development without writing any source code (so-called low-code development).

As shown in FIG. 2, the action table 106a includes, for example, a control (control type) that is an element displayed on the screen, an event (event type) executed for the control, and an event execution The action (action type), which is a specific process performed during or after execution, setting availability identification information (availability) for identifying whether the action setting is appropriate or inappropriate, and error identification information (error code ) and including. In short, the action table 106a is a table for managing information on the actions that can be set. The setting propriety identification information (usability) is information indicating that the action setting is appropriate ("○" in FIG. 2) or information indicating that the action setting is inappropriate ( 2, it is "x").

For example, as shown in Figure 2, it is inappropriate to set the action type "Message box activation" for the control type "text box" and the event type "value change". The error code "Error6" is set. On the other hand, as shown in Figure 2, it is appropriate to set the action type "Tool tip display" for the control type "text box" and the event type "value change". ” is set.

The correspondence table 106b includes, for example, the error identification information (error code), error messages, etc., as shown in FIG. Preferably, the error message contains information on the appropriate action to be set. For example, in the error message "Cannot set message box activation on text value change event. Please display errors and warnings with tooltips.", the part "Please display errors and warnings with tooltips." , corresponds to the information of the appropriate action to be set.

The control information 106c holds the object information (control model) of the control in an array. The control information 106c includes, for example, an identification key, a type, a child element key, an identification name, etc., as shown in FIG. An identification key is a unique key numbered within the system. Type is the type of control. A child element key is an array of identification keys that can be its own child element. A distinguished name is a unique key set by the user.

Next, the logic flow information/action information 106d holds logic flow object information (logic flow model) in an array. In the logic flow model, object information (action model) of the actions and an object (flow model) for controlling the execution order are held in an array.

The logic flow information/action information 106d has, for example, a plurality of logic flows, and further has a flow and the action for each logic flow.

In the example of the logic flow information/action information 106d shown in FIG. 5, as a plurality of logic flows, the "button click processing" identified by the identification key "logic flow key 1" and the identification key "logic flow key 2" are identified. "Value change processing" is set. In the example of the logic flow information/action information 106d shown in FIG. 5, a flow and an action are set for "button click processing".

The flow includes an execution source action key, a next execution action key, a callback key, and the like, as shown in FIG. The execution source action key is the identification key of the action that is the source of the processing execution order. The next execution action key is an identification key of an action to be executed after the action indicated by the execution source action key is executed. A callback key is a key to determine the action selected by the user at runtime (for example, if the user selects Yes in a message box, the Yes flow is specified and the action according to the end key is executed). is done).

Actions include identification keys, types, and the like, as shown in FIG.

Next, the event information 106e is information that links the event that can be set to each control and the logic flow, and holds the object information (event model) of the event in an array. The event information 106e includes, for example, a type, a control identification key, an event type, a logic flow identification key, etc., as shown in FIG. The type is a value indicating whether the event is a screen event or a control event. The control identification key is the identification key of the control model. The event type is the type of event to be executed. A logic flow identification key is an identification key of a logic flow model.

In the example of the event information 106e shown in FIG. 6, the setting of the column labeled "event model" on the right side will be described. , "control key 3 (corresponding to the text box as shown in FIG. 4)" is set, and "logic flow key 2 (corresponding to value change processing as shown in FIG. 5)" is set as the logic flow identification key ing. Therefore, in this column, an event "value change" and a logic flow "value change process" are set for the text box.

The control unit 102 is a CPU or the like that controls the system development support apparatus 100 in an integrated manner. The control unit 102 has an internal memory for storing a control program such as an OS, a program defining various processing procedures, required data, and the like, and performs various information processing based on these stored programs. Run.

The control unit 102 functionally conceptually includes, for example, a screen information check unit 102a, an event information check unit 102b, and a logic flow information check unit 102c. The logic flow information check unit 102c further includes, for example, a control that is an element displayed on the screen, an event that is executed for the control, and a specific process that is executed during or after the execution of the event. refer to an action table for managing information on the actions that can be set, including the actions, setting propriety identification information for identifying whether the action setting is appropriate or not, and error identification information; a control selected by the developer, an event set by the developer for the selected control, and an event set by the developer for the selected event during system development. an acquisition unit 102c1 as acquisition means for acquiring setting permission/prohibition identification information and error identification information associated with an action, and information indicating that the setting permission/prohibition identification information obtained by the acquisition means is inappropriate for the action setting. , a display unit 102c2 as display means for displaying an error message corresponding to the error identification information acquired by the acquisition means.

The screen information check unit 102a checks screen information.

The event information check unit 102b checks event information.

The logic flow information check unit 102c checks logic flow information.

The acquisition unit 102c1 refers to the action table 106a (see FIG. 2) that includes the control type, the event type, the action type, the usability, and the error code. Get the availability and error codes associated with the selected control, the event set by the developer for the selected control, and the action set by the developer for the selected event do.

If the usability acquired by the acquisition unit 102c1 is information indicating that the setting of the action is inappropriate ("x" in FIG. 2), the display unit 102c2 changes the error code acquired by the acquisition unit 102c1 to Display the corresponding error message.

[3. Overview and flow of processing]
In this item, the outline of the processing according to this embodiment will be described in [3-1], and the flow of processing according to this embodiment will be described in [3-2].

[3-1. Overview of processing]
In this section, an outline of processing according to this embodiment will be described. The overall image of the check in this embodiment is as shown in FIG. 7. The "check process" is executed based on the screen information, and the check result is returned to the developer.

As for the timing of the check processing in this embodiment, it is executed asynchronously at any time at the timing when the setting is changed. The reason for making it asynchronous is to allow developers to proceed with configuration changes even while checking is in progress.

The target of the check processing in this embodiment is screen information (control information, logic flow information, action information and event information).

As result information of the check processing in this embodiment, an error code and an error message are returned to the developer. Multiple error codes and error messages may be returned.

[3-2. Process flow]
In this section, the flow of processing according to this embodiment will be described with reference to FIGS. 8 to 10. FIG. In this embodiment, control information, event information, logic flow information and action information are checked in this order. Errors detected during check processing are stacked as error codes in the "error code stack".

(1) Screen Information Check First, the screen information check will be described with reference to FIG.

The screen information check unit 102a checks the control information (step S1 in FIG. 8). Specifically, "whether there is an inconsistency in the parent-child relationship" and "whether an illegal property is set" are checked.

If there is an inconsistency in the parent-child relationship, or if an invalid property is set (NG in step S1 in FIG. 8), the screen information checking unit 102a adds the detected error to the error code stack (see FIG. 8). step S2).

On the other hand, if the check result is OK (OK in step S1 of FIG. 8), the process proceeds to FIG. 9, and all the events defined in the screen information are checked in order.

(2) Checking Event Information Next, checking event information will be described with reference to FIG.

The event information check unit 102b checks whether the identifier of the set control exists in the control information 106c (step S3 in FIG. 9).

If it does not exist (NG in step S3 of FIG. 9), the event information check unit 102b adds the detected error to the error code stack (step S4 of FIG. 9), and the process ends (END).

On the other hand, if it exists (OK in step S3 of FIG. 9), the event information checking unit 102b holds the control type. Then, the event information check unit 102b checks whether the set logic flow identifier exists in the logic flow information/action information 106d (step S5 in FIG. 9).

If it does not exist (NG in step S5 of FIG. 9), the event information check unit 102b adds the detected error to the error code stack (step S6 of FIG. 9), and the process ends (end).

On the other hand, if it exists (OK in step S5 of FIG. 9), the process proceeds to FIG. 10 and the target logic flow information is checked. At this time, the control type and event type are passed to the logic flow check.

(3) Checking Logic Flow Information Finally, checking logic flow information will be described with reference to FIG.

The logic flow information check unit 102c checks "whether there is a break in the logic flow" and "whether an unnecessary flow is drawn" (step S7 in FIG. 10).

If there is a break in the logic flow, or if an extra flow is drawn (NG in step S7 of FIG. 10), the logic flow information check unit 102c adds the detected error to the error code stack (see FIG. 10 step S8).

If there is no break in the logic flow and no unnecessary flow is drawn (OK in step S7 of FIG. 10), the logic flow information checking unit 102c sequentially checks all the actions defined in the logic flow. (Step S9 in FIG. 10).

Specifically, the logic flow information checking unit 102c acquires the action type of the action to be processed (step S10 in FIG. 10). Subsequently, the logic flow information checking unit 102c extracts the information on availability and the error code from the action table 106a of FIG. can be obtained (step S11 in FIG. 10). Note that step S11 is a characteristic process in the present invention, so the following [4. Specific example of processing].

If it cannot be acquired (NG in step S11 of FIG. 10), the logic flow information check unit 102c adds the detected error to the error code stack (step S12 of FIG. 10).

If it has been acquired (OK in step S11 of FIG. 10), the logic flow information checking unit 102c checks the action information (step S13 of FIG. 10). Note that step S13 is a characteristic process in the present invention, so the following [4. Specific example of processing].

If the check result is NG (NG in step S13 of FIG. 10), the logic flow information checking unit 102c adds the detected error to the error code stack (step S14 of FIG. 10).

On the other hand, if the check result is OK (OK in step S13 of FIG. 10), the logic flow information checking unit 102c checks whether there is an unchecked action (step S15 of FIG. 10).

If there is an unchecked action (NG in step S15 of FIG. 10), the logic flow information checking unit 102c returns to step S9 of FIG. 10 and continues processing until there is no unchecked action.

On the other hand, if there is no unchecked action (OK in step S15 in FIG. 10), the process ends (END in FIG. 10).

[4. Specific example of processing]
In this section, a specific example of processing according to this embodiment will be described mainly using FIGS. 2 to 3 and FIGS. 11 to 17. FIG.

The present invention relates to a setting check mechanism when setting processing for controls in a low-code development tool. In this section, we will specifically explain how an error will be displayed if inappropriate settings are made when the developer performs low-code development from a screen where controls are placed.

[4-1. Control Selection and Event Settings]
First, as indicated by the arrow (left side) in FIG. 11, the developer selects "text box" as a control for setting an event.

Next, as indicated by the arrow (right side) in FIG. 11, the developer sets "value change" as an event, and presses the "OK" button at the bottom right of the screen.

[4-2. Create logic flow]
Next, as shown in FIG. 12, a logic flow called "value change process 1" is created. At this time, behind the scenes, a control event is generated that associates the control with the logic flow.

[4-3. Logic flow settings]
Next, in this item, setting of detailed contents about the logic flow created in [4-2] will be explained.

First, as shown in FIG. 13, an action of "execute API" is arranged by the developer.

Next, as shown in FIG. 14, "branches" are placed by the developer.

In the following, the case where the action placed after "branch" is "start message box" and the case where it is "display tool tip" will be described separately.

(1) When "start message box" is placed First, as shown in Fig. 15, when the action "start message box" is placed by the developer (when an error is displayed due to inappropriate settings ) will be described.

Here, in this example, as described in [4-1], the event "value change" is set for the control "text box", and the action performed during "value change" is As explained, "Message Box Launch" was placed.

From the action table 106a of FIG. 2, the acquisition unit 102c1 acquires the availability "x" and the error code "Error6 ” is obtained. In other words, the placement of the action "start message box" is inappropriate.

When the acquisition unit 102c1 acquires the availability "x", it further determines from the correspondence table 106b in FIG. Please show errors and warnings in tooltips."

Then, the display unit 102c2 displays the error message acquired by the acquisition unit 102c1 on the screen as shown in FIG. The reason why an error message is displayed when "activate message box" is arranged is as follows. That is, when the value of the text box is changed, the state of the screen is being changed, so interrupt processing such as that of the message box is stressful for the user.

As described above in item (1), according to the system development support device 100 according to the present embodiment, it is possible to prevent the setting of inappropriate actions, and at the same time, allow the developer to arrange appropriate actions. can be proposed to

(2) When "Show tooltip" is placed Next, as shown in Fig. 16, when the action "Show tooltip" is placed by the developer (no error is displayed due to appropriate settings) processing will be described.

Here, in this example, as described in [4-1], the event "value change" is set for the control "text box", and the action performed during "value change" is As explained, "Tooltip display" was placed.

The acquisition unit 102c1 acquires availability “o” as information associated with the control type “text box”, the event type “value change”, and the action type “tool tip display” from the action table 106a of FIG. I don't get the code). In other words, the placement of the action "show tooltip" is appropriate. A "tool tip" is a kind of display element in the operation screen of a computer, and is an annotation displayed around an object when a cursor or mouse pointer is placed on the object. In the example of FIG. 17, the tool tip is a square with the text "The item has not been entered."

When the availability of "O" is acquired, naturally, no error message is displayed, and the developer can continue low-code development.

[5. Summary of this embodiment]
As described above, according to the system development support device 100 according to the present embodiment, in system development performed by a developer setting an action to be executed on a screen used by a user, inappropriate setting of the action can be prevented. can be prevented.

Here, since the act of developing a system by programming has a high degree of freedom, there is a possibility that response processing that is inappropriate for user operations may be described. In addition, even conventional low-code development tools do not have a function to suppress usability deterioration during configuration and make proposals, and there is a risk that usability will deteriorate depending on how to make it. In other words, in conventional low-code development, even if the necessary functionality is satisfied, there are many cases where the quality at the time of system use is not taken into consideration.

Therefore, in this embodiment, for example, by providing a mechanism for controlling the processing that can be set for the event of the control and proposing an appropriate processing, the screen and behavior that are not appropriate as a response to the user's operation can be displayed. On the other hand, it has become possible to prevent the development of inconsistent screens. In other words, in this embodiment, for example, it is possible to set an event for a control that can be set for each screen operation function, and furthermore, at the timing when the control is operated, it is determined whether or not the arrangement is illegal. , making it possible to immediately detect incorrect placement.

As a result, in this embodiment, for example, in low-code development, it is possible to consider the quality when using the system after satisfying the required functionality. The system developed based on the mechanism of this embodiment is expected to improve usability and make system utilization more efficient.

In addition, the present embodiment can contribute to the reduction of disposal loss and the promotion of paperless and computerization.

In addition, since this embodiment can contribute to strengthening control and governance, it is possible to contribute to Goal 16 of the SDGs.

For example, among the processes described in the embodiments, all or part of the processes described as being automatically performed can be manually performed, or all of the processes described as being manually performed Alternatively, some can be done automatically by known methods.

In addition, unless otherwise specified, the processing procedures, control procedures, specific names, information including parameters such as registration data and search conditions for each process, screen examples, and database configurations shown in this specification and drawings can be changed arbitrarily.

Also, with regard to the system development support apparatus 100, each illustrated component is functionally conceptual, and does not necessarily need to be physically configured as illustrated.

For example, the processing functions of the system development support device 100, particularly the processing functions performed by the control unit, are implemented in whole or in part by a CPU and a program interpreted and executed by the CPU. Alternatively, it may be implemented as hardware using wired logic. The program is recorded on a non-temporary computer-readable recording medium containing programmed instructions for causing the information processing apparatus to execute the processing described in this embodiment, and system development support is performed as necessary. It is read mechanically by the device 100 .
