Aplicativo android para conferência de valor de compras e criação de listas

Abstract

This final paper describes the development of the smartphone application "Mercadinho", whose main function is to calculate the value to be paid of a purchase, based in a list of products created by the user beforehand. Large supermarkets work using different computer systems in order to avoid frauds. Be these frauds committed by malicious employees, clients, or by legit inattention. In other hand, smaller markets still need to find ways to grant the final value of the products at the final step of the purchase, offering a concern to the client. To help in the solving of this problem a mobile app, a website and a shared database were created. To do this, various technologies were used in different steps of the development process, like database systems, agile methodologies, web services, Java, PHP, version control systems, among others. The Technologies used are described and explained throughout the subsequent chapters. So, we believe that is possible to hit the proposed problem with mobile technology, which is having its use always more inherent to modern society each day.
