Abstract
In a market dominated by many mobile applications for all purposes, there is currently no visible application of cultural content or commercial content to support the tourist when traveling to Mirandela. Such applications currently available to the tourism industry are limited in content and cultural offerings, and commercial applications only communicate with their partners and have no cultural content.This work presents a framework of a mobile application implementation to support the tourist information needs when he is visiting Mirandela in which interest points are combined with commercial content.This solution allows the tourist to have only one application that integrates the contents that he wishes/subscribe, both cultural and commercial, creating a parametrizable universal profile that can be accessed by any of the entities in the system. In addition to the tourist benefiting from this solution that facilitates the exploration of interest points in Mirandela, the entities involved in the system will also benefit because they are able to increase the dissemination of their products and/or services and thereby increase their market potential and consequently their sales.
