The MySQL GUI team, under the leadership of graphical guru Mike Zinner, has posted a new beta version of MySQL Workbench. This is a brand new graphical tool targeted to DBAs giving them a powerful graphical environment for modeling and managing database schemas. This is an awesome tool that makes it easy to reverse engineer huge database schemas, maintain the model graphically, and it provides complete 2-way synchronization between the graphical model and the underlying database schema. It provides automatic layout, customizable views, drag and drop capabilities and more.
MySQL Workbench runs on Windows, Mac and Linux and takes advantage of the native interface on each platform. Performance is awesome even for very large models with thousands of tables. Workbench has an extensible architecture via an underlying scripting engine and a cool plug-in interface. You can also import models from DBDesigner4, Mike's earlier modeling tool.
Workbench is a graphical tool, so words fail me in describing how cool this is. Really, just download it, check it out, and post to the forums to let us know what you think.
