IT systems are essential for the operations of any modern business. Such systems must support operations of their corresponding company under any conditions. Disaster Recovery (DR) strategies have been implemented to help organizations mitigate unexpected failures and reduce unnecessary expenses. However, to the best of our knowledge, no other work experimentally analyzes data replication at the database layer with a focus on DR strategies. Therefore, this work evaluates a relational database replication as a mean of implementing a DR solution. We use a real testbed in a public cloud environment to perform extensive experiments aimed at implementing the replication provided by MySQL, considering various scenarios in the context of DR. Our results show how response time, Recovery Point Objective (RPO) and Recovery Time Objective (RTO) vary according to the size of the replicated data, the synchronization type (ex.: asynchronous or semisynchronous) and the configuration of the slave servers. This work can assist DR coordinators or individuals to decide which database replication configuration for disaster recovery is best for their work environment.
Sistema integrado para registro de aulas e análise de frequência dos alunos do Projeto Conecta Vidas do Centro Tecnológico da Associação Conexão Social

The Social Connection Association (ACS), founded in 2005 in Lagoa de Itaenga, Pernambuco, has the mission of guaranteeing the rights of people in situations of social vulnerability through education and inclusion. The Conecta Vidas Project aims to promote digital literacy and physical activities for the elderly, contributing to their active aging and strengthening community bonds. However, the registration of attendance and the documentation of activities face significant challenges, such as the logistics of real-time records and the security of sensitive beneficiary data. This report presents a proposal for a responsive Integrated System for Class Registration and Attendance Analysis, developed with React, Node.js and MySQL technologies. The proposed solution seeks to optimize attendance registration, facilitate the secure storage of photos and simplify the flow of information for coordination. This is intended to improve the efficiency of educators, ensure data protection, and provide detailed and accurate reporting to funders. The system aims not only at the continuity and success of the project, but also at the promotion of a more transparent and effective management, enhancing the benefits offered by ACS.
