HeidiSQL is a graphical user interface (GUI) application specifically designed for managing MySQL databases. Unlike command-line tools, HeidiSQL provides a visual representation of your database structure, making it easier to navigate tables, view data, and perform various database operations. It's a powerful tool for both beginners and experienced database administrators. You can connect to MySQL servers using HeidiSQL's connection settings, which include details like host, port, username, and password. Once connected, you can explore the database schema, browse tables, and execute SQL queries. HeidiSQL offers features like data import/export, query building, and data manipulation tools, streamlining database tasks. It's a valuable asset for anyone working with MySQL databases, offering a more intuitive approach compared to using SQL commands directly in a terminal.
