4. Users Translator View recent document submissions Download documents to translate Submit translated version of the document

5. Users Manager Add new users to the system Remove users from the system View customer activity summaries View translator productivity reports

6. Server and Development Environment Apache HTTP server for Windows XP MySQL Database Server Server side scripting in PHP World Wide Web Consortium’s XHTML and CSS compliance

7.

29. System Testing Repeated attempts to break the site and cause errors Explore every possible scenario a user may encounter Simulate everyday use of system Providing “bad input” to verify system will not allow the user to present errors

30. System Testing After verifying the input produced desirable results within one user interface, test the results caused by the same input within the other interfaces Some not so obvious errors are caught by checking the web server and database server logs

31. Future Work Multilingual support for all user interfaces Separate database tables for each user class to simplify user interfaces Addition of a new user class: Admin or Super user Support for monetary transactions (Pay Pal, Credit Card, etc)
