... 156 SQLite Perl Tutorial .............................................................. 158 DBI Interface APIs .................................................................................. 158 Learning SQLite Perl Tutorial Installation The SQLite3 can be integrated with Perl using Perl DBI module, which is a database access module for the Perl programming language. It defines a set of simple steps to install DBI module on your Linux/UNIX machine: $ wget http://search.cpan.org/CPAN/authors/id/T/TI/TIMB/DBI-1.625.tar.gz $ tar xvfz DBI-1.625.tar.gz $ cd DBI-1.625 $ perl Makefile.PL

equivalent 60 db_info dbi; // default ctor required if (main_site_is_available) { get_data(main_site, dbi); } // overwrite default value else { get_data(backup_site, dbi); } // overwrite default d is now okay } db_info dbi = uninitialized; if (main_site_is_available) { get_data(main_site, dbi); } // construct else { get_data(backup_site, dbi); }

(update/delete)；例如 Spark 计算时， 需要预先将数据装载到 DataFrames 模型中； 基本上都缺少索引和存储过程等特征 除 HAWQ 外，大多对于 ODBC/JDBC/DBI/OLEDB/.NET 接口的支持 有限，与主流第三方 BI 报表工具的兼容性不如 MPP 数据库 SQL-On-Hadoop 不擅长于交互式（interactive）的 Ad-hoc 查询， 大
