Developed software allows you to visualize and manage data from NB-IoT devices. The application receives data about the current device location. It allows users to select their device to be monitored and stores the data in a database from which they will then load into Google Maps. The visualization service allows the user to track the current location and also view the exact path history of the selected device. The software is developed in the Java programming language using the Spring and Hibernate frameworks, allowing good maintainability, operating system independence, and easy scalability.
