Desenvolvimento de sistema de colaboração em massa para reduzir gastos dos consumidores com compras de supermercado

Abstract

This work presents a web system that was developed with the intent of reducing its users’ expenses with the acquisition of supermarket goods. The system compares the prices of products being sold in different supermarkets, which were previously fed into a database by the users themselves, in a mass collaboration scheme, by means of a web based interface. When performing the rice comparison, the user marks the products that s/he intends to buy and the system checks the data base, making the required comparisons and calculations to determine where it is more beneficial to purchase each product on its own and the set of products all together. This allows the user to choose the supermarket that will provide the largest savings. The products of this work are the system’s modeling and its development in PHP, using MySQL as the database.
