Nowadays, traveling to other countries has become cheaper and more affordable, so people travel more than before, so there is a growing need for basic and detailed information about countries. Driven by the lack of a web application that brings together more information in one place in an intuitive user interface, I decided to develop an application that displays as much detail and as much relevant data related to all countries of the world. In order to realize the idea, diagrams are first drawn that clearly explain the functionality and role of the application. In addition to the diagrams, a prototype application is complex to visually represent the idea of ​​the interface. After that, the focus was on the structure of the data and the initial filling of the database with concrete information so that the web would have concrete and useful content in the very beginning. The design is made to be as intuitive and simple as possible. The web application contains different areas of information such as the cost of living and the size of the population. The information within some areas is very dynamic, so it is possible to be constantly entered and changed by users and corrected by administrators. Everything was done through a web application to make the application available on as many different platforms as possible. The goal of the application is to provide users with easier and faster access to the most detailed information of the selected country. In order to create a large database, it is possible to easily enter data for very dynamic information such as, for example, data on cost of living. The result of the project is an application that allows users to easily enter and view general information from all countries of the world.
