INTEGRIDADE DE DADOS NO CONTEXTO DE UM SISTEMA PARA GESTÃO DE COBRANÇA

Abstract

This work aims to analyze the importance of data integrity in the development in context of a system for billing management, highlighting the challenges and solutions adopted to ensure data consistency, security, and reliability. The study was conducted through the practical implementation of a system in a controlled environment using Google Colab, employing symmetric encryption with the AES algorithm to protect sensitive data. Use case and entity-relationship diagrams (ERD) were developed, and performance tests were carried out involving encryption and decryption operations with different iteration volumes. Results showed that the algorithm's execution time grows linearly with the number of operations, maintaining efficient and symmetrical performance. Challenges such as handling concurrent transactions, real-time validation, and integration with external payment APIs were also identified. It is concluded that applying encryption alongside good software engineering practices is essential to guarantee data integrity in financial management systems, contributing to security, compliance with regulations such as LGPD, and user trust in the system.
