What can i use to create db scheme in eclipse?

I want to create db scheme in eclipse, but dont know what can i use for this. I try ERMaster http://ermaster.sourceforge.net/content/manual/en/index.html#3.1. . But it looks terrible. Can you tell me simple plug in for eclipse what can import db and show it's scheme?

How do I open a database in eclipse?

Select Window > Open Perspective > Other. Choose Database Development from the list. In the Data Source Explorer view, right-click the Databases folder and choose New. In the New Connection Profile dialog, choose SQL Model-JDBC Connection, and click Next.

ER-diagram-editor for eclipse

Also this one isn't bad, but is not a plugin or extension for eclipse.
