Sistema web para negociação e doação de bens usados

Abstract

E-commerce has been widely used by companies with several objectives such as reaching new markets (overcoming geographic barriers) and providing facilities of purchase to consumers (convenience, price comparison, agility, purchase from home). For small businesses and individuals, having an e-commerce system (which includes the website to advertise the products and the system to carry out the commerce transactions itself and logistics) may not be financially advantageous due to its cost. One way to benefit from the advantages of this type of commerce, minimizing its inherent expenses, is the use of electronic markets and e-marketplaces that, in a very simple way, bring together sellers who use a common platform to promote and negotiate products and services. Using the e-marketplace concept, a system was developed aiming to offer a web system in order to use goods that can be offered for sale, exchange, donation and/or loan. Goods offered for sale or donation can be sold and the resulting value can be destined to assist entities previously registered in the system and chosen by the user who owns the good. To implement the system, the main technologies used were the Java language, the ecosystem Spring (Boot, Data, Security, andWeb), the Angular framework, and PostgreSQL database.
