Abstract

MÉTODO PARA ACESSO SELETIVO DE DADOS, MÉTODO E SISTEMA PARA COMPACTAÇÃO DE DADOS. A presente invenção refere-se a um método para compactar dados que inclui obter um esquema de compactação personalizado para um formato de um arquivo de texto delimitado, e ao usar o esquema de compactação para analisar o arquivo de texto delimitado em uma pluralidade de blocos de dados, dividir cada um dos blocos de dados em uma pluralidade de unidades de dados para acesso seletivo eficiente, e compactar a pluralidade de unidades de dados na pluralidade de blocos de dados com o uso de diferentes algoritmos de compactação para uma razão de compactação aprimorada. O arquivo delimitado é dividido em uma pluralidade de blocos de dados com base nas definições de região no esquema. Cada um dentre a pluralidade de blocos de dados é dividido na pluralidade de unidades de dados com base em seu respectivo tamanho de unidade de dados especificado no esquema. A pluralidade de unidades de dados em cada bloco de dados da pluralidade de blocos de dados é compactada com o uso dos diferentes algoritmos de compactação indicados pelas instruções de compactação no esquema. O arquivo compactado consiste em blocos de dados compactados, um esquema de compactação e vários metadados para descompactação de dados, reconstrução de arquivos e funcionalidades como segurança de dados e solicitação de pesquisa. O arquivo de texto delimitado pode incluir informações genômicas ou outro tipo de informação.
