MQT is an HTML5 application which allows browsing and querying of SQL databases, currently supporting MySQL and PostgreSQL. It may be viewed as rather simple-minded competition to phpMyAdmin, with a focus on getting SELECT queries done just right and tuned to blazing performance.
termsql converts text from stdin or any file into an SQLite database table and allows users to execute SQL queries on that table, all in just one line on the command line. It can be used to sort, display, convert, extract, and modify data on the command line using syntax familiar to those who know SQL.
