  7. Web based GUI Tools to manage MySQL
    For light-weight quick tasks, SIDU is my favorite tool. People having Windows will find HeidiSQL very useful to manage MySQL, in fact, In my opinion, this is better than popular PhpMyAdmin which looks slow comparatively and have less features. I like Navicat a lot but itís paid, SQLyog is also worthy which is though paid but a community edition exist here.
