Technical Field

[0001] The present invention relates to an application providing system, an application providing method, and an application providing program.

Background Art

[0002] In recent years, low-code development has been known, in which an application program can be quickly developed by visually operating a GUI (Graphical User Interface) to combine screen components or logic components without describing source code as much as possible. Application programs developed by low-code development are used for data analysis in a business environment, but it is necessary to expand data across other items for analysis and perform flexible layout and UI control accordingly.

[0003] Patent Document 1 describes an application screen display program implementation method in which an information processing device executes application software to display a screen, and holds a master table for controlling the display of display elements constituting the screen. Each record of the master table for controlling the display of the display elements holds information related to variables in the source code of an execution program associated with the control of the display of the display elements, and each record of the transaction data input / output from the display elements holds information related to variables in the source code of an execution program associated with the display elements (see, for example, Patent Document 1).

MODE FOR CARRYING OUT THE INVENTION

[0012] Embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments.

[0013] [1. Overview] Figure 2 shows an example of a business execution screen provided by a business application. Business applications used for data analysis in a business environment expand data across multiple items for analysis. Depending on the analysis, the number of data columns may become variable, for example, as shown in Figure 2, such as execution screen MA-1 where the table-type data in the details section has 4 columns for April to June, or execution screen MA-2 where it has 6 columns for April to August.

[0014] When developing using low-code development tools, it is difficult to change the number of columns in response to screen operations because layout information must be set in advance. In the case of changing the monthly column as shown in Figure 2, it is possible to change the number of columns by setting constraints such as a maximum of 12 months, determining the starting month and the number of months to display, and hiding unnecessary columns according to the conditions, but the setup cost is high. However, when deploying actual departments in columns, it is not possible to set an upper limit, so it becomes impossible to change the number of columns to display.

[0015] In the application provision system 100 of this embodiment, when binding table-type data obtained by logic flow, etc., to details, a setting is provided in the detail control to duplicate the definition information of the last column set by the developer, making it possible to display the UI control of the definition information of the last column even when the number of columns in the table-type data changes.

[0016] Figure 3 illustrates the binding of table-type data to the detail control. When the obtained data D1 is bound to the execution screen MA-3, if the number of columns in data D1 is the same as the number of columns set by the developer, the UI control of the set definition information, such as column width, left / right centering, comma spacing, integer / decimal digit control, and click events are reflected and displayed on the execution screen MA-4. In the application provision system 100 of this embodiment, even if the number of columns in the obtained data is greater than the number of columns set by the developer, the definition information of the last column of the table-type data of the detail control set by the developer is obtained, and the UI control of the definition information of the last column set by the developer is reflected and displayed in the columns from the last column onward of the obtained table-type data. For example, as with data D2 in Figure 3, even if the number of columns is greater than the number set by the developer, the setting information of the last column (April) of the definition information can be duplicated and applied to the columns from the last column onward (May and June) to apply the UI control and event settings. In addition to click events, events that validate cell values ​​(amount, etc.) can be exemplified as events.

[0017] [2. Structure] Referring to Figure 1, an example of the configuration of the application provisioning system 100 (Web server) according to this embodiment will be described. Figure 1 is a block diagram showing an example of the configuration of the application provisioning system 100. As shown in Figure 1, the application provisioning system 100 of this embodiment can be configured, for example, with a low-code platform (low-code development platform / low-code execution platform). Alternatively, it may be configured with a no-code platform.

[0018] The application provisioning system 100 comprises a control unit 102, a communication interface unit 104, a storage unit 106, and an input / output interface unit 108. Each part of the application provisioning system 100 is connected to communicate via any communication path.

[0019] The communication interface unit 104 connects the application provisioning system 100 to the network 300 via communication devices such as routers and wired or wireless communication lines such as dedicated lines. The communication interface unit 104 has the function of communicating data with other devices via communication lines. Here, the network 300 has the function of connecting the application provisioning system 100 to web clients (including web clients used by web clients used by web clients (users)) 200... and business systems not shown, which can communicate with each other, and is, for example, the internet or a LAN (Local Area Network). The data stored in the storage unit 106, which will be described later, may be stored in a data server not shown.

[0020] The input / output interface unit 108 is connected to an input device 400 and an output device 500. The output device 500 can be a monitor (including a home television), a speaker, or a printer. The input device 400 can be a keyboard, mouse, microphone, or a monitor that works in conjunction with the mouse to provide pointing device functionality. In the following, the output device 500 may be referred to as the monitor 500, and the input device 400 as the keyboard 400 or mouse 400.

[0021] The memory unit 106 stores various databases, tables, and files. The memory unit 106 also stores computer programs that work in cooperation with the OS (Operating System) to give instructions to the CPU (Central Processing Unit) to perform various processes. As the memory 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.

[0022] The memory unit 106 includes a development application DB 106a for storing various setting information during the development stage, a business application DB 106b to which the application information of the development application DB 106a is made public, and the like.

[0023] The development application DB106a stores layout definitions, event assignment definitions, logic flow definitions, etc.

[0024] A layout definition is a table that defines the layout of a screen created by a developer. As shown in Figure 11 as an example, a layout definition specifies the control ID, identifier name, type, list of child element IDs, and properties.

[0025] The event assignment definition is a table that links the control ID, which identifies the element controls that make up the screen, the type of event for the area that can be specified on the screen, and the logic flow ID, as shown in Figure 13 as an example.

[0026] A logic flow definition includes control information, action information, and logic flow information. As shown in Figure 14 as an example, each logic flow ID stores the action ID, type, and unique settings, as well as the flow ID, source, and destination.

[0027] The control unit 102 is a CPU or similar component that comprehensively controls the application provisioning system 100. The control unit 102 has internal memory for storing control programs such as the OS, programs that define various processing procedures, and required data, and executes various information processing based on these stored programs.

[0028] Functionally, the control unit 102 comprises a setting unit 102a and an execution unit 102b.

[0029] The configuration unit 102a functions as a low-code development platform, creating configuration information (definitions) related to the provision of business applications and registering it in the development application DB 106a.

[0030] For example, the configuration unit 102a provides a layout configuration screen in response to a request from a Web client 200 (developer), and creates a layout definition and registers it in the development application DB 106a based on the developer's actions on the configuration screen.

[0031] Furthermore, the configuration unit 102a provides a logic flow configuration screen in response to a request from the Web client 200 (developer), and creates event assignment definitions and logic flow definitions in response to the developer's operations on the configuration screen, and registers them in the development application DB 106a.

[0032] Furthermore, the configuration unit 102a provides an action setting screen, such as an API call, in response to a request from the Web client 200 (developer), and registers the individual definitions of the configured actions in the development application DB 106a based on the developer's operations on the action setting screen.

[0033] The execution unit 102b functions as a low-code execution platform and provides business applications in response to requests from Web clients 200 (users).

[0034] When the execution unit 102b receives a startup command from the Web client 200 (user), it starts the business application. Specifically, the execution unit 102b acquires the layout definition, event assignment definition, and logic flow definition, expands them into the definition information memory, generates user-specific control information data, expands it into the execution unit memory, and returns the screen HTML, the scripts necessary for event operation, and event assignment information to the user.

[0035] Here, user-specific control information data refers to some of the property information of a control that may change depending on the user. As shown in an example in Figure 22, user-specific control information data stores the control ID, type, and properties.

[0036] Furthermore, in response to a request from the Web client 200 (user), the execution unit 102b obtains a logic flow ID corresponding to the requested event control ID from the event assignment definition, reads the logic flow definition of the obtained logic flow ID, executes the logic flow, and when binding the obtained table type data to the detail control, obtains the definition information of the last column of the detail control's table type data set by the developer from the layout definition, and displays the obtained table type data from the last column onward by reflecting the UI control of the definition information of the last column set by the developer.

[0037] [3. Prerequisites for Processing] This section describes the prerequisites for the processing according to this embodiment.

[0038] [3-1. Overall diagram of the low-code platform] Low-code platforms consist of a configuration screen operated by developers and an execution screen operated by users.

[0039] Figure 4 illustrates the process performed by developers on the settings screen MB-1. On the settings screen MB-1, developers configure layout and event handling settings using drag-and-drop operations with the mouse (400). The information from the settings screen is stored in the development application DB106a.

[0040] Figure 5 illustrates the user's processing on the execution screen MA-6. Based on instructions on the execution screen MA-6, the low-code infrastructure reads the configuration information set on the settings screen, expands it into memory on the Web server 100, and allows it to be executed as an application on the Web server 100 and as a web page (screen + program) for the Web client 200 (user). The Web page (screen + program) for the Web client 200 (user) can be configured to be sent from the Web server 100 to the Web client 200 (user) and executed when loaded into the Web browser of the Web client 200 (user). The program for the Web page of the Web client 200 (user) may be implemented using well-known Web application technologies (for example, a format including instructions and runtime variables written in JavaScript®).

[0041] [3-2. Settings screen] This section provides a detailed explanation of how to configure settings on the settings screen.

[0042] (1) Layout editing screen First, the Web client 200 (developer) edits the layout of the execution screen using the settings screens MB-2 to MD-6 shown in Figures 6 to 10. In the settings screen MB-2 in Figure 6, the properties of the detail input control are selected and the "Repeat last column depending on data" command is checked. When the "Repeat last column depending on data" command is turned on, the definition information of the last column of the table-type data of the detail control set by the developer, such as UI control, is extended to the columns after the last column of the obtained table-type data.

[0043] In the settings screen MB-3 shown in Figure 7, clicking the detail control displays popup P1. Columns can be added, deleted, or duplicated by selecting options in the popup.

[0044] In the settings screen MB-4 shown in Figure 8, after adding a column, clicking on a cell displays popup P2 (Change Cell Type). Clicking popup P2 displays popup P3, allowing you to change the cell's category and type. In Figure 8, the cell type has been changed to numeric.

[0045] In the settings screen MB-5 shown in Figure 9, the column names have been changed, and the properties of the clicked numerical cell are modified. UI control is set by specifying properties in the settings screen MB-5 shown in Figure 9.

[0046] In the settings screen MB-6 shown in Figure 10, processing is assigned to the cell click event. In Figure 10, the click event is assigned as the processing when the monthly amount label cell is pressed, but it is also possible to set it to a double-click event, etc. Based on the above settings, a layout definition is generated. The generated layout definition is shown in Figure 11.

[0047] (2) Logic flow setting screen Next, Web client 200 (developer) configures the process when the display button is pressed in the logic flow configuration screen MB-7 shown in Figure 12. By configuring the API call action flow as circled in Figure 12, the user moves to the action configuration screen described later. In the API call action, by binding the obtained table-type data, a repeating detail is set with the last column having an expanded definition. Note that the logic flow configured here is not limited to API calls; any action that sets table-type data in the detail is acceptable. For example, setting CSV data in the detail control is also acceptable. The event assignment definition generated by this configuration screen is shown in Figure 13, and the logic flow definition is shown in Figure 14. Furthermore, Web client 200 (developer) configures the process when the monthly amount label cell is pressed in the logic flow configuration screen MB-9 shown in Figure 18. By configuring the dialog display action flow as circled in Figure 18, the user moves to the action configuration screen described later.

[0048] (3) Action settings screen Next, the Web client 200 (developer) configures the API call in the action configuration screen MB-8 shown in Figure 15. In the action configuration screen MB-8 shown in Figure 15, "Monthly Data Acquisition API" is selected as the API, and the arguments and return values ​​are set by drag and drop. Figure 16 shows an example of the individual definition of the monthly data acquisition API generated by the action configuration screen MB-8 in Figure 15. As shown in Figure 16, since the API arguments and return values ​​are set in the individual definition, the table-type data obtained by the API call is returned to the client. Figure 17 is a diagram illustrating the arguments and return values ​​obtained by the API call. When an event with an API call configured is requested, the execution unit 102b receives the department code and monthly period specified in the individual definition and acquires table-type data from the business application DB 106b as shown in Figure 17.

[0049] Furthermore, Web client 200 (developer) configures the dialog display settings in the action settings screen MB-10 shown in Figure 19. In the action display screen MB-10 shown in Figure 19, "Expense Breakdown Dialog" is selected as the dialog, and the arguments to be passed to the launch destination are configured. Figure 20 shows an example of an individual definition of the dialog display generated by the action settings screen MB-10 in Figure 19.

[0050] [4. Processing] [4-1. Startup Process] Figure 21 is a diagram illustrating the startup process flow of the application provision system 100 in the embodiment. Upon receiving a startup command from a Web client 200 (user), as shown in Figure 21, the Web server 100 acquires definition information such as the layout definition (control list) shown in Figure 11, the event assignment definition shown in Figure 13, and the logic flow definition (flow definition, action definition) shown in Figure 14, and expands it into the definition information memory (S1). Subsequently, it generates information to be held per execution user (user-specific control information data (see Figure 22)) from the acquired definition information and expands it into the execution unit memory (S2). After that, it returns the HTML of the screen, the script necessary for event operation, and the event assignment information shown in Figure 23 to the user (S3).

[0051] [4-2. Processing when the display button is pressed] Figure 24 illustrates the processing flow when a user presses a display button. For example, when Web client 200 (user) presses (clicks) the display button with control ID "1-7", Web client 200 (user) checks if the event assignment information sent contains control ID "1-7" and event name "click". If the event assignment information sent contains control ID "1-7" and event name "click", it requests event information from Web server 100. If the event assignment information sent does not contain control ID "1-7" and event name "click", the process terminates.

[0052] Figure 25 illustrates the server-side processing flow when a request is made by a user. When a request is made from Web client 200 (user) for control ID "1-7" and event name "click", the logic flow ID "LID0" corresponding to control ID "1-7" and event name "click" is obtained from the event assignment definition, and the logic flow ID "LID0" from the logic flow definition is read and executed (S11).

[0053] Here, the logic flow ID "LID0" is the monthly data acquisition process (API call), and the monthly data acquisition process (API call) is executed (S12).

[0054] Figure 26 illustrates the processing flow for acquiring monthly data. After identifying the monthly data acquisition API (S21), the control sets values ​​for the API arguments according to the individually defined argument settings shown in Figure 16 (S22), and then executes the API (S23). The API return value obtained according to the return value setting is then set in the control (S24).

[0055] Figures 27A, 27B, and 27C illustrate the process flow for setting API return values ​​into controls. The table-type data obtained as API return values ​​is set into the detail controls on the execution screen.

[0056] In the user-specific control information data deployed in the execution unit memory, the column cell list has two columns: column index: 0, label name: department code, cell content alignment: left-aligned, and column index: 1, label name: month, cell content alignment: right-aligned. The data cell list has two columns: column index: 0, cell content alignment: left-aligned, and column index: 1, insert commas every 3 digits: true, cell content alignment: right-aligned. In addition, data D4 in the execution unit memory only has a string label and the data is empty.

[0057] The table data is bound to the detail control on execution screen MA-7. Depending on the number of columns in the bound table data D3, additional columns will be displayed on the screen. The column indexes of the table data D3 are mapped to the column indexes on the screen, and the data is displayed. Execution screen MA-8 is after the table data D3 has been bound. The detail control displays with the number of columns and data corresponding to the columns and data of the table data increased. The user-specific control information data deployed in the execution unit memory also has increased column cell lists and data cell lists to match the bound table data D3. The added column cells and string label cells are set to the user-specific control information data with their default settings. Empty data in the execution unit memory is updated with the bound data D5.

[0058] After binding the table-type data D3, the system checks if "Repeat last column" is enabled in the layout definition expanded in the definition information memory. If it is enabled, the definition information for the last column is identified. The identified definition information is then reflected in the columns following the last column. Since the last column has column index: 1, the definition information for column index: 1 is reflected in the columns from column index: 1 onward, i.e., column indexes: 2 and 3. Here, in the column cells (column indexes: 2 and 3), the alignment of the cell contents is set to "right-aligned," the data cells (column indexes: 2 and 3) are changed to "numeric label cells," "Insert commas every 3 digits" is set to "on," and the alignment of the cell contents is set to "right-aligned." The identified information (UI control) for the last column is reflected in the detail controls of the execution screen MA-9. In addition, in the user-specific control information data deployed in the execution unit memory, the alignment of the cell contents in the column cells is changed to "right-aligned," the data cells (column indices 2 and 3) are changed from "text label cells" to "numeric label cells," "insert commas every 3 digits" is turned "on," and the alignment of the cell contents is changed to "right-aligned."

[0059] Here, we will briefly explain how to identify the definition information of the last column. Figure 28 is a diagram illustrating the process of identifying the definition information of the last column of a table-type data.

[0060] Referencing the definition information memory, the detail header panel is identified from the child element information of the target detail control (S31). In the definition information memory in Figure 28, the first child element "ID2-2" is the detail header panel. Next, the column cells are identified from the child element information of the identified detail header panel (S32). In this case, the column cells are "ID2-2-1 to ID2-2-2".

[0061] Among the identified column cells, the value with the largest column index is used as the final column index (S33). In this case, column index : 1 is the final column index.

[0062] By using the identified last column index, the column cells and data cells that match the last column index can be identified from the column cell list and data cell list of the memory of the execution unit of the detail control (S34), and the definition information of the last column can be identified by obtaining the definition information of those cells.

[0063] After performing the monthly data acquisition process as described above, the HTML for the screen, the scripts necessary for event execution, and event assignment information are returned to the user. The event assignment information sent is the event assignment information after the monthly data acquisition process.

[0064] Figure 29 shows an example of event assignment information after monthly data acquisition processing. If extended cells exist, the assignment information for the detail control cells is duplicated for the increased column indexes, as shown in Figure 29. In Figure 29, for column indexes 2 and 3, where "Repeat last column according to data" is turned on in the detail control on the execution screen, the event assignment information for column index 1, which is the last column, is duplicated and added.

[0065] Figure 30 illustrates the method for duplicating allocation information for extended cells. First, it is determined whether "Repeat last column" is enabled in the layout definition deployed in the definition information memory. If it is enabled, the definition information memory is referenced, and the detail data panel is identified from the child element information of the target detail control (S41). In the definition information memory of Figure 30, the second child element is the detail data panel. Next, the data cells are identified from the child element information of the identified detail data panel (S42). In this case, the data cells are "ID2-3-1~ID2-3-2".

[0066] Among the identified data cells, the value with the largest column index is designated as the last column index. In this case, column index: 1 is the last column index. The cell with the identified last column index set is designated as the last column data cell (S43). In this case, "ID2-3-2" is the last column data cell.

[0067] Next, it is determined whether an event assignment has been made to the last column data cell (S44). If there is a last column data cell in the event assignment definition, the event assignment information is duplicated in the execution unit memory for data cells with a column index greater than that of the last column data cell (S45). In this case, the column index of the last column data cell is 1, and the assignment information of the detail control cell is duplicated for data cells (numeric label cells) with a column index greater than 1.

[0068] [4-3. Processing when the monthly amount label cell is clicked] Figure 31 illustrates the process when the monthly amount label cell is clicked. In the execution screen MA-10 of Figure 31, the process when Web client 200 (user) selects control ID "2-1", column index "2", row index "1", and event name "click" is described below.

[0069] Figure 32 illustrates the processing flow when the monthly amount label cell is clicked. The Web client 200 (user) checks if the sent event assignment information contains control ID "2-1", column index "2", and event name "click". If the sent event assignment information contains control ID "2-1", column index "2", and event name "click", it requests event information from the Web server 100. If the sent event assignment information does not contain control ID "2-1", column index "2", and event name "click", it terminates the process.

[0070] Figure 33 illustrates the server-side processing flow when the monthly amount label cell is clicked. When a request is received from Web client 200 (user) for event control ID "2-3-2" and event type "click", the logic flow ID "LID1" corresponding to control ID "2-3-2" and event name "click" is obtained from the event assignment definition, and the logic flow ID "LID1" from the logic flow definition is read and executed (S51). Subsequently, the dialog display process is executed (S52).

[0071] After performing the dialog display process as described above, the HTML of the screen, the script necessary for event operation, and event assignment information are returned to the user (S53). Upon return, the execution screen MA-11 of the cost breakdown dialog shown in Figure 34 is displayed on Web client 200 (user).

[0072] In the application provisioning system 100 of this embodiment, as described above, even for data with a variable number of column items, the pre-configured UI control can be dynamically extended, and the UI control can be reflected and displayed even for a number of column items that exceeds the pre-configured layout. Furthermore, configured events can also be extended and reflected for a number of column items that exceeds the pre-configured layout.

[0078] Furthermore, the processing procedures, control procedures, specific names, information including parameters such as registration data and search conditions for each process, screen examples, and database configuration shown in this specification and in the drawings may be changed at will unless otherwise specified.

[0079] Furthermore, with respect to the application provisioning system 100, each component shown in the diagram is a functional concept and does not necessarily need to be physically configured as shown.

[0080] For example, the processing functions of the application provisioning system 100, particularly those performed by the control unit, may be implemented in whole or in part by a CPU and a program interpreted and executed by the CPU, or they may be implemented as wired logic hardware. The program is recorded on a non-temporary computer-readable recording medium containing programmed instructions for causing the information processing device to execute the processing described in this embodiment, and is mechanically read by the application provisioning system 100 as needed. That is, a storage unit such as ROM or HDD (Hard Disk Drive) records a computer program that works in cooperation with the OS to give instructions to the CPU and perform various processing tasks. This computer program is executed by being loaded into RAM and works in cooperation with the CPU to constitute the control unit.

[0081] Furthermore, this computer program may be stored on an application program server connected to the application provisioning system 100 via any network, and it is possible to download all or part of it as needed.

[0082] Furthermore, the program for executing the processing described in this embodiment may be stored on a non-temporary computer-readable recording medium, or it may be configured as a program product.

[0083] Furthermore, "program" refers to a data processing method described in any language or writing method, regardless of its format, such as source code or binary code. Note that "program" is not necessarily limited to a single, monolithic structure; it also includes distributed structures consisting of multiple modules or libraries, and those that work in cooperation with other programs, such as an operating system, to achieve their functions. Regarding the specific configuration and reading procedures for reading the recording medium in each device shown in the embodiments, as well as the installation procedures after reading, well-known configurations and procedures can be used.

[0084] The various databases stored in the memory unit are storage means such as RAM, ROM, other memory devices, hard disks, flexible disks, and optical disks, and store various programs, tables, databases, and web page files used for various processes and website provision.

[0085] Furthermore, the application provisioning system 100 may be configured as a known personal computer or workstation or other information processing device, or as an information processing device to which any peripheral devices are connected. Alternatively, the application provisioning system 100 may be implemented by installing software (including programs or data, etc.) that enables the processing described in this embodiment on the device.

[0086] Furthermore, the specific forms of distribution and integration of the devices are not limited to those shown in the illustration, and all or part of them can be configured by functionally or physically distributing and integrating them in any unit according to various additions or functional loads. In other words, the embodiments described above may be implemented in any combination, or the embodiments may be implemented selectively. [Industrial applicability]
