Enhancements:
- A tactics editor was added, allowing you to develop your tactics directly in the field designer.
- Real units of measure can be used, so 32px will represent whatever unit of measure you define.
- When you create a new field layout, you can set the size of the field, which will be shown while drawing the field.
- Fields can be exported to SVG, BMP, JPEG, or PDF.
- The last page of the field creation wizard does not work correctly under Win32.

DB Designer Fork is a fork of the fabFORCE DBDesigner 4. DBDesigner is a visual database design system that integrates entity relationship design and database creation.

The project generates SQL scripts for Oracle, SQL Server, MySQL, and FireBird.

PyDBDesigner is a free relational database modeling tool that is planned to be able to design both logical and physical models similarly to Erwin(c) and PowerDesigner.

Its goal is to provide a useful toolset that allows developers analysts and database designers to design and develop databases from the verbal model to the schemas and SQL scripts.

There is no such a tool is available as a freeware. There is a project called DbDesigner, but it seems to be discontinued and its functionality is not enough for modeling (and the concept behind it seems to be weak).

The concept is to implement ER logical and physical modeling paradigm as correctly as possible, meanwhile creating a tool that is useful as soon as it is possible. So the development concept is that features are added rapidly, but carefully (trying to leave space to the features that come later).

For example, the "type" class is good enough to implement data domains, however, the code that actually creates domains using GUI is not implemented. The "type" attribute of the properties uses this object, so adding domains to attribute types is easy.

iReport project is a powerful, intuitive and easy to use visual report builder/designer for JasperReports written in 100% pure java.
This tool allows users to visually edit complex reports with charts, images, subreports,.... iReport is integrated with JFreeChart, one of the most diffused OpenSource chart library for java.
The data to print can be retrieved through several ways including multiple JDBC connections, TableModels, JavaBeans, XML, etc...
Enhancements:
- Full support for JasperReports 1.3.4.
- A new XML field mapping tool.
- A new document structure outline.
- Improved refactoring capabilities.
- An improved report query dialog.
- An improved UI with sortable tables.
- Several bugfixes.

WAusers application is one component of the WAhelper Web accessibility testing suite.

WAusers serves for managing Web accessibility testing sites where users can register, create their own Web accessibility testing projects, and log into all their projects using a single global password.

Web pages are often designed without handicapped users in mind. Despite there exist Web accessibility guidelines such as W3C Accessibility Guidelines or U.S. Section 508 law, many Web designers are not aware about problems they cause to handicapped visitors of their pages. And even when a Web designer tries to make Web pages accessible, he may not be aware about all the obstacles handicapped users can meet.

- Software tools can be helpful here. Several Web accessibility checking tools already exist, but they have various problems:
Most of them are non-free and you cant use them freely to evaluate accessibility of your website effectively. Making things accessible means removing barriers and it is important to make the barriers as low as possible.
- New tests usually cant be added easily. An easily extensible and freely modifiable tool is needed so that its features can be improved efficiently. A good and maintained tool can make the whole process of making Web pages accessible more effective.
- The tools often dont try to go beyond semi-automated tests. But there are many accessibility problems which cant be detected, diagnosed and reported without human assistance. A tool helping humans with the testing process is needed.
