Abstract

"REGISTRANDO-SE PARA, E RECUPERANDO, INFORMAçãO DE ALTERAçãO DE TABELA DE BANCO DE DADOS QUE PODE SER USADA PARA INVALIDAR ENTRADAS DE CACHE". Um servidor proporciona respostas da Rede que podem incluir conteúdo a partir de tabelas de dados em um banco de dados. O servidor mantém um cache (por exemplo, na memória de sistema) que pode armazenar conteúdo (incluindo conteúdo a partir de tabela de dados) de modo a aumentar a eficiência de subseq³entemente proporcionar o mesmo conteúdo para satisfazer às solicitações de cliente da Rede. O servidor monitoriza as tabelas de dados em relação a alterações e, quando ocorre uma alteração em uma tabela de dados específica, invalida as entradas armazenadas em cache que dependem de uma tabela de dados específica. Além disso, em resposta a uma solicitação de cliente da Rede para uma resposta da Rede, o servidor atribui uma dependência de cache de banco de dados a pelo menos uma parte de uma resposta elaborada da Rede (por exemplo, para conteúdo recuperado a partir de uma tabela de dados) com base em comandos executados durante elaboração da resposta da Rede. A pelo menos uma parte da resposta elaborada da Rede é subseq³entemente armazenada em cache em um local de cache no servidor.
