Are you asking about SAS Data Integration from an assistive technology standpoint or just in general?
While you can perform certain data integration general tasks using Base SAS and Enterprise Guide, SAS does offer specific, specialized data integration software, including the Enterprise Data Integration Server. You can learn more here: http://www.sas.com/technologies/dw/
I attempted to access the specified SAS user guide documentation and, as far as I can tell, the SAS documentation pages are inaccessible to screen reader users. The screencasts video demonstrations use Flash movies, which include no accessibility features or audio description. The "SAS Data Integration Studio 4.21: User's Guide New 4/28/09" HTML link cannot be activated by the keyboard Enter key or Shift Enter keys, but rather appears to require a Mouse click. When I downloaded the PDF version of the user document, it appears only the first page is readable by a screen reader. How do blind users, who depend upon braille/speech screen reader technology, access SAS learning materials?
As I shared with you in an earlier email, to follow up on your documentation accessibility questions, I met with the Tech Pubs accessibility liaison (to R&D).
Thank you, again, for identifying the accessibility issues with that 9.2 documentation set. The 9.1 set is the version applicable to your project, and it can be found here: http://support.sas.com/onlinedoc/913/docMainpage.jsp.
Personally, I had difficulty expanding the nodes in the tree pane via keyboard
To get to the content, I moved focus into the content frame, posted the context menu (Shift+F10 in my browser) and opened the content page in a new window (frameless). You may have better luck with this as well.
