ERDesigner NG
The Mogwai ERDesigner is an entity relationship modeling/design tool(ERD) such as ERWin and co. The only difference is that it is Open Source and does not cost anything. It was designed to make database modeling as easy as it can be and to support the developer in the whole development process, from database design to schema and code generation.
Mogwai項目的ERDesigner工具是一類似於ERWin的實體關係建模、設計工具。唯一與之不同的是，ERDesigner是開源的，您不需要花費一分錢。設計ERDesigner的目的在於使得數據庫建模儘可能低簡單，並試圖在整個開發過程中支持開發者，即從數據庫設計到模式、代碼的生成。
ERDesigner NG- is based on Java and can be run on Windows,Unix and Mac systems
- 基於Java，使用Java語言編寫，可以再Windows、Unix和Mac系統上運行。當然，Linux也是可以的，任何有Java虛擬機的地方都是可以的。
- is distributed as a zip/tar/installer file or can be launched by WebStart
- 以zip\tar\安裝文件的形式發佈，或者通過WebStart來啓動。
- has a powerful WYSIWYG editor for physical database design
- 對於物理數據庫設計，有一個強的的所見即所得的編輯器。
- supports 2D and 3D database modeling, browsing and design
- 支持2D和3D的數據庫建模，可以瀏覽和設計這些炫目的效果。
- generates true 3D anaglyphic views from your database structure
- 能夠由數據庫架構生成真實的3D分析視圖。
- handles tables, relations, views, domains, custom types, indexes and comments

- supports schema conversion between different dialects
- analyzes the database model for common problems
- 能夠分析數據庫模型的常見問題。在模型生成Sql語句時，可以先分析、檢查下模型的建立是否存在問題。
- generates OpenXava applications
- it is based on GPL license
- support is available by authors and newsgroups
