Ondrej Zara and his tem at Openlink Software have created a Openlink Software JS Toolkit, known as OAT. It is a full-blown JS framework, suitable for developing rich applications with special focus to data access.

OAT works standalone, offers vast number of widgets and has some rarely seen features, such as on-demand library loading (which reduces the total amount of downloaded JS code).

OAT is one of the first JS toolkits which show full OpenAjax Alliance conformance: see the appropriate wiki page and conformance test page.

There is a lot to see with this toolkit:

You can see some of the widgets in a Kitchen sink application

Sample data access applications:

• SQL Query By Example
• Forms designer
• DB Designer

OAT is Open Source and GPL’ed over at sourceforge and the team has recently managed to incorporate our OAT data access layer as a
module to dojo datastore.
