Abstract
The purpose of the present thesis is the development of a first aid system, that includes an Android application for the end user and a Web Service for the communication with the database. The application contains information on providing first aid regarding the emergency, as well as the capability of persisting the user’s location on the database in order for special assistance to arrive. The application does not communicate directly with the database, but the Web Service ensures this communication as an intermediate. For the development of the aforementioned software, full-stack technologies needed to be studied, meaning, ones that provide the capabilities of developing all functions, starting from the front-end, the user’s graphical interface, all the way to the back-end, the communication with the database and the data transportation. For the user part, as mentioned, an Android application was decided to be developed. The Web Service software uses the REST architecture for the communicaton with the database and lastly for the storage of the data the Google Firebase platform was chosen, which among others services, provides a non relational database. The data are saved in JSON format and are available in real time.
