OpenLink AJAX Toolkit

OAT (OpenLink AJAX Toolkit) offers a broad Javascript-based, browser-independent widget set for building rich user interfaces on all common browsers. It comes with sample applications for interactive SQL query composition and database design. These applications work against any Microsoft XML for Analysis (XML/A) servers, such as OpenLink Virtuoso and others.
