The mobile Android app of the travel tracking system

Abstract

The conceptual model of the subject area and the architecture of the travel support system have been developed, namely the planning of the travel itinerary regarding the interaction with the user of the system. It is proposed architecture of the mobile Android application that was designed by reference to specific features of the client-server architecture and is flexible because it is not limited to use the specific software solutions: frameworks or libraries. The proposed system belongs to the class of travel support systems and enables the user to create, edit, and delete elements of the travel itinerary. The system also targets multiple users with one itinerary at a time. Each user has the ability to create multiple itineraries at one time. You can add multiple users to one itinerary at a time, thus creating many-to-many relationships. The architecture of the mobile Android application is the implementation of client-server architecture with an approach to REST network protocol architecture that provides access to information resources on a local or global network. The information is sent to the server part of the clients, where it is processed and stored in a PostgreSQL relational database. For practical implementation, Java programming language, ORM technology, JSON data format, and Android platform were used. One of the main functions of the developed system is the construction of the itinerary taking into account the factors of the interaction of many users and the factors that they have chosen as the most important. The proposed results are of practical importance and can be used in other areas related to logistics.
