SQLyog provides a powerful Graphical User Interface (GUI) for MySQL, allowing you to quickly and easily administer your databases with the minimum of fuss. It is made by Webyog Softworks and can be downloaded from www.webyog.com.
The software is available for free although you can choose to upgrade to the Enterprise Edition. The price for this ranges from $39 for a single user, non-commercial licence to $999 for unlimited users. The Enterprise Edition includes a multitude of extra options, but if you just want a graphical way to create, edit and modify your databases the you'll find the free edition to be fine. Being free, it does ask you to upgrade, but the message is unobtrusive and infrequent - only displaying a short bit of text when you load and close the program.
The software itself is well layed-out with a simplistic grey design. Simply enter your server's connection details and SQLyog will connect to it and show you the available databases in the left hand pane. You can then view your tables and create and delete databases to your heart's content. Editing content is quick and easy with your data being displayed in spreadsheet format, meaning you can quickly modify many database rows at a single time.
The graphical nature of SQLyog makes it quicker and easier to use than the browser-based PHPMyAdmin, and it's just as powerful. For free, what more could you want?
