Resumo


Os Sistemas gerenciadores de banco de dados (SGBD) implementam um algoritmo de substituição para determinar quais dados trocam entre as memórias principal e secundária. Esses algoritmos estão em constante evolução. Podemos estar iniciando uma nova era desses algoritmos com avanços extensivos no aprendizado de máquina. Este artigo propõe o algoritmo EBRES (Efficient Buffer Replacement with Exponential Smoothing) para incorporar uma política de substituição de página inteligente baseada em um modelo de previsão de baixa sobrecarga para prever acessos futuros a dados.
Palavras-chave: gerenciamento de buffer, política de substituição, memória flash, aprendizado de máquina
