Sistema de gerenciamento de replicação para PDV (Ponto de Venda) de multi lojas

Abstract

As a company evolves, the volume of data grows every day, and it is critical for any company to rethink its organization, identifying necessary improvements and anticipating the company's ability to operate in an agile and consistent manner over the years. The present work presents the development of an asynchronous replication management system, using a PostgreSQL database. The objective is to replicate data from a system responsible for closing the sales of consumers who come directly to the store to buy. All data is centralized in a central server and each computer contains only the data needed to issue an invoice. For the elaboration of this system, the architectures used for the replication of Bidirectional and Client-Server data are briefly presented. The replication management system presented good results, ensuring data reliability and consistency. [resumo fornecido pelo autor]
