Information schema

  • abstract: In relational databases, the information schema is an ANSI standard set of read-only views which provide information about all of the tables, views, columns, and procedures in a database. It can be used as a source of the information which some databases make available through non-standard commands, such as the SHOW command of MySQL, the DESCRIBE command of Oracle, and the \d command of PostgreSQL.

双语例句

  • Rather than mapping columns to instance variables in application code or a mapping file, ActiveRecord generates them dynamically at runtime based on your database's information schema.

    相比于把“列”映射成程序代码或映射文件中的实体变量，ActiveRecord是在运行中基于你的数据库schema动态生成映射的。

    youdao
