FIG. 56 shows a screen in which elements of a sliced form are separately defined as a "slice.html" Represents a directory screen that is stored as a file separated by separate HTML.

Hereinafter, a method of providing an application development environment according to an embodiment of the present invention will be described with reference to FIGS.

4 is a flowchart illustrating an application development environment providing method according to an embodiment of the present invention.

Referring to FIG. 4, the application development environment providing apparatus 100 first creates an application project (S101).

The application development environment provision apparatus 100 can generate an application project for development of an application. The application project may include various information constituting the application to be developed. The application project may include identification information of the application to be developed, version information, developer information, authentication information, image information, database connection information, server connection information, module information, and source information. And the like.

To this end, the application development environment provision apparatus 100 may provide an application project creation screen.

FIG. 5 shows an application project creation screen provided by the application development environment provision apparatus 100. FIG.

As shown in FIG. 5, the developer can create an application project through an input to the application project creation screen. The application project creation screen may include an application ID input unit, authentication information and profile input unit, and an application image input unit, as shown in FIG. This minimizes the input information that the developer has to input and minimizes the required image.

In particular, when an application project is created and a development target platform is set, the application development environment providing apparatus 100 can perform automatic resizing and automatic version management of an application page accordingly.

Then, the application development environment providing apparatus 100 displays a first screen showing a connection relationship among a plurality of pages (S103).

The application development environment providing apparatus 100 can display page information of an application being developed by the generated application project through the first screen. The first screen may indicate the connection relationship between the respective pages.

On the other hand, the screen can be divided into frames for a relatively large tablet-specific smart device, such as a smart phone, and basic settings can be configured to configure the application.

58 shows a screen for dividing a frame for a tablet-dedicated device displayed by the application development environment provision apparatus 100. Fig.

It provides a development environment to support inter-frame movement components for tablet-specific smart devices, action components between frames, and data movement components between frames.

6 shows a first screen 110 displayed by the application development environment providing apparatus 100. As shown in FIG.

As shown in FIG. 6, the first screen 110 may represent a connection relationship to a plurality of pages included in an application under development in an application project. Each page may represent each electronic document that may be displayed when an application is running on the terminal 300. [ The electronic document displayed on the terminal 300 by the application operation can be switched according to the connection relationship between the respective pages. Such a conversion or movement can be performed by the event generation of the component described above and the action action accordingly.

For example, as shown in FIG. 6, an application may include a Home page, a Card page, a Find page, a Donut page, an SNS page, and a View page. The first screen 110 may include a plurality of arrow images 111 indicating connection relationships between the respective pages. Each arrow image 111 may represent a movement or a conversion relationship between the respective pages.

In particular, the application developer may modify the inter-page connection relationships as desired by modifying or deleting each arrow image 111 displayed on the first screen 110. [ For example, a developer could link new arrows to link between pages. Also, you can delete existing arrows to break between pages.

If there is a change or deletion of the arrow image, the application development environment providing apparatus 100 can reflect the change or deletion of the image of the arrow in the application code configured in the intermediate language. Therefore, application developers can easily grasp and modify the connection relationship between each page without expert knowledge of code modification.

Meanwhile, the application development environment providing apparatus 100 may display a form tab 112 for setting a connection relationship between pages or adding a page to the first screen 110. The form tabs 112 may include predefined icons, for example, for establishing connection relationships and adding pages.

In addition, when the icons are moved to the first screen 110, the application development environment providing apparatus 100 may set a connection relationship or add a predefined page corresponding to the corresponding icon Can be performed.

4 will be described again.

Then, the application development environment providing apparatus 100 displays a second screen showing a connection relationship between the components on one page (S105). Then, the application development environment providing apparatus 100 connects the first component including the event information and the second component including the action information (S107).

As described above, a page may include a plurality of components. Each component may refer to a unit object that is responsible for each screen or function within a page. In addition, the components may include event information or action information for performing such a screen or function.

The event information may include events generated by a predetermined user input to the terminal 300 or an operation of the terminal 300. For example, events may include onClose, onInit, onScrollMouse, onClick, onError, onSuccess, or onEnd events.

Each of the events may correspond to action information included in another component. The action information may include information on an operation of an application that is performed according to an event generated in the terminal 300. [ For example, the behavior of an application that is performed according to an event can include running, hiding, showing, toggling, paging, clear, goHome, goBack, bind or next commands of a particular component.

As described above, event information or action information included in each component may correspond to each other, and the connection relation therebetween may be displayed on the second screen.

7 shows a second screen 120 according to an embodiment of the present invention.

As shown in FIG. 7, the second screen 120 may represent each component and may represent a connection relationship between event information and action information included in each component.

In particular, each component in the second screen 120 may be displayed in a respective block form. The action information included in each component may be displayed in the form of a text box on one side of the block, and the event information may be displayed in the form of a text box on the other side of the block.

Then, the connection relation between each box can be indicated by an arrow image. Each arrow image can be started from a specific event of a specific component, and can be directed to a specific action of another component. In this case, the arrow image may indicate that the action of the component to be executed next when a specific event occurs.

As described above in the first screen 110, the application developer can change or delete the image of each arrow on the second screen 120, and each component may be added or deleted by a drag-and-drop method. Accordingly, the connection relationship between the event and the action of each component can be changed, and the application development environment providing apparatus 100 can display the component displayed on the second screen 120 and the application Can be generated or deleted.

For example, the button1 component block 121 may include an onClick event box 123, and the onClick event box 123 may include a goBack action box 124 included in the link1 component block 122 by an arrow image Can be connected. In this case, the application development environment providing apparatus 100 may generate a code in an intermediate language so that the goBack action of the link1 component is performed when an onClink event for the button1 component is generated, and insert the code into the application code under development. Therefore, the developer can establish the connection relationship between the components by only manipulating the user interface without understanding the code.

8 is a diagram showing a relationship between a second screen and an actual code according to the embodiment of the present invention.

8, according to an exemplary embodiment of the present invention, an application developer generates a component messagebox1 to be executed next when an onClick event of a Button1 component is generated in the second screen 120, and an action show, You can specify by connecting. In this case, the application development environment providing apparatus 100 can automatically generate a code similar to the box portion of the lower half code in Fig. 8 and insert it into the application code. Therefore, the developer can set the connection between the event and the action of the desired component by manipulating the user interface without writing the connection relation between the event and the action by writing the JAVA code.

9 is a view for explaining an action list of the second screen 120 according to an embodiment of the present invention.

Referring to FIG. 9, the application development environment providing apparatus 100 may display a one-to-one relationship between an event and an action in an arrow image on the second screen 120. However, There are limitations to doing so.

Accordingly, according to an embodiment of the present invention, the second screen 120 may further include an action list component block 125 to solve this problem. The action list component block 125 may refer to an intermediate component inserted between components to perform a plurality of actions corresponding to one event.

For example, the developer may create an action list component block 125 and associate an arrow image so that the execute action of the action list component block 125 is executed in response to one event (onClink) ~ event9) can be generated. Then, the developer can designate the components and actions to be executed by each of the plurality of events (event1 to event9) using the arrow image again. In FIG. 9, the hide action of the panel1 component is performed in response to the event 1, and the show action of the message box 1 is set to be performed in response to the evnet2.

The application development environment providing apparatus 100 may generate a code configured in an intermediate language so that the connection relationship established in the second screen 120 may be executed in the application as shown in the lower part of FIG.

Accordingly, when the application is executed in the terminal 300, when the user clicks Button1 by the connection relationship set in the second screen 120, the operation of hiding panel1 and showing messagebox1 is performed.

FIG. 10 shows a method of displaying a component block and a connection relationship in an application development environment providing apparatus 100 according to another embodiment of the present invention.

Referring to FIG. 10, the application development environment providing apparatus 100 may display a component block screen 140 showing the component blocks included in the page together with the page screen 130.

The page screen 130 may represent a page image implemented by each of the components.

In addition, the component block screen 140 can display a connection relationship between components, events, and actions in a tree structure. Each component can be represented by a depth, and the lower depth of each component can contain actions that the component contains. Accordingly, the developer can easily select a desired component and an action.

The attribute information of the selected component or action may be displayed at the top of the component block screen 140. The attribute information may include identification information of each component or action, data connection information, and event information associated with each action.

The component block screen 140 and the page screen 130 may correspond to the second screen 120 described above. Accordingly, the application development environment providing apparatus 100 can select and display the same application from the second screen 120, the component block screen 140, and the page screen 130. [ To this end, the application development environment providing apparatus 100 may provide a setup menu for the connection relationship display method of the component.

The connection establishment method between events and actions may be a method of selecting an event and an action included in each component, unlike the event processing method through double click and procedure creation in the existing development environment. Accordingly, when the developer presses a specific button, the connection between the event and the action can be completed only by selecting a component object to be executed and an action included in the object.

On the other hand, FIG. 59 shows a screen for setting on a component to which a connection relationship between components is branched when an event and an action occur according to a condition in a second screen configuration by adding a branch (if) component.

The comparison branch of the component can be compared with the value of the constant and the database and can be branched. If the value is a constant value, the user can input the value directly to branch between the components. It can also be configured to take advantage of predefined constants and system environment variables.

11 is a diagram for explaining a method of adding a component of an application development environment providing apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 11, the application development environment providing apparatus 100 may display a predefined component list 150 that can be added to the page screen 151. The component list 150 may include a plurality of component items. Each component item may correspond to each component code having a predefined function or screen.

Then, the developer can select any one of these component items and move them to the page screen 151 in a drag-and-drop manner. Correspondingly, the application development environment providing apparatus 100 can facilitate adding a component by inserting a code corresponding to the moved component item into the application code. This allows developers to add components to a page with a simple drag and drop without having to write code for the component during application development.

In addition, the predefined components may be received and updated from the server 200. The application development environment providing apparatus 100 can communicate with the server 200 to receive new components and update the component list. The developer can add new components to the application page by dragging and dropping from the updated component list.

FIG. 12 shows a data binding method of an apparatus 100 for providing an application development environment according to an embodiment of the present invention.

As shown in Fig. 12, a component may include a data component (dbtable1, data_store). A data component can be connected to a DB on the Web via SQL or RESTful / SOAP, and can represent an object that can receive and display data from a connected DB. The application development environment providing apparatus 100 can provide a binding for DB connection to the data component so that the developer can perform data binding between the application and the DB without knowledge of SQL or RESTful / SOAP .

FIG. 13 shows a relational database management system (RDBMS) setting method of an application development environment provision apparatus 100 according to an embodiment of the present invention.
