The Map API (Application Program Interface) provided by the conventional portal service is a method of applying a prepared function. On the other hand, the data access library 170 according to the embodiment of the present invention provides a function of including a navigation function in a basic map API, modularizing the library according to functions, and further writing a desired function by the developer himself.
This method is possible because the application program development system according to the embodiment of the present invention manages classes by layers to lower the degree of coupling with other classes so as not to affect other classes, Because it is encapsulated in proprietary technology and designed in a way that developers can create.
The first class 110 is a class that supports the path search function.
The first class can provide a basic route search function, i.e., a function of searching for a route from a departure point to a destination and guiding the route. Furthermore, it can provide route search option function such as recommendation route, shortest route, high-speed route, and free route providing function reflecting the real-time road traffic situation. Such a route search function can be provided separately for vehicles, for walking, and for public transportation.
The route search class is a technique for finding the optimal route from the origin to the destination considering the road state information. It is a class that provides a function to search various optional routes by fusing various information of the road data to the basic A * to be.
In addition to being able to be used as a path search class itself, the path search class inherits the path search class through object-oriented overriding (redefining class member functions) technique so as to apply each data and algorithm of each developer , It is designed as a structure that can override the path search member function and execute the developer's own algorithm. At this time, the data structure is designed to use a data access class so that the data structure designed by the developer can be used.

The search class according to the embodiment of the present invention supports the initial search of the navigation and the full name search as the class that provides the basic search function of the navigation. Other searches can be configured by the developer. You can use the search class to move the map to the location, and you can use the search results as a starting point, destination, and waypoint of the route search.
With these search classes, the developer can easily provide location information search functions to various LBS tasks in areas that utilize maps, or in non-use areas.
The sixth class 160 is a class that supports user interface development. The sixth class can support functions of processing various UIs such as various types of images such as a mouse, a keyboard, a touch input, and the like.
The UI / UX class is a class that manages the configuration of the screen separately from the map display class. A button for performing various functions of navigation, a display position of contents, and a movement of a screen and a screen are performed. In the UI / UX class according to the embodiment of the present invention, a screen configuration is produced using a separate tool .
Furthermore, since UI / UX class is responsible for various user input processing, the developer can manage the entire screen without any effort even if it is processed only for the function execution, and the screen configuration can be divided into the design area So that the labor involved in development can be minimized.
Using the sixth class distinguishes the screen design from the other development, so the developer can infect the development without burdening the screen design, and the screen design can easily reflect various ideas and customer requirements There is an effect.
According to the embodiment of the present invention, a plurality of classes as described above can be individually and individually driven with integrity, and can be separated from each other.
