Desenvolvimento do Back-End de Compra e Venda de alimentos em cantinas universitárias

Abstract

Online solutions to reduce queues in food businesses cause increased productivity for sellers and convenience for consumers. Microentrepreneurs in this area, such as university cafeteria owners, have few resources to use popular applications in the market. In this context, this paper reports the development of a software back-end for buying and selling food in university cafeterias, with the objective of filling this gap in the market, providing the owners of small establishments with a viable solution to accelerate the sales process and provide their customers with an alternative to avoid queues. The web application called OnTime uses open source technology to provide a reliable solution for smartphones, integrated with a secure payment system through API and modular code for better maintenance and scalability. This report presents the Model-View- Controller design pattern, Java technologies for web, concepts of secure communication and databases, the methodological procedures used to develop the proposed solution, its detailed description, the tests performed, as well as the results and suggestions for further work.
