This tool is indispensable for database modeling and maintenance. The database structure and schema can be designed and exported into MySQL DB. The existing database tables can be imported into this tool too. The saving format is XML.
Other is the very popular PHPMyAdmin. The latest version offers many good features like stability in import and export functions and documentation and indexing utilities.
MySQL AB also offers an utility for MySQL database administration; but it’s not stable as it’s an ALPHA release. The features looks promising however!
