2. System Overview
A system is needed to facilitate the interactions between the customers, translators, and managers of an online translation service.
Must be implemented as a web interface to extend the service to users worldwide.

3. Users Customer Receive translation quotes
Upload documents, specifying document information such as target and original languages and urgency of translation
Monitor progress of submissions
Download translated documents upon completion
Provide quality ratings for completed translations

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. Security Requirements
Protect user’s identities by securing database as well as sessions
MySQL server configured to only accept local connections using named pipes
Limited session lifetime
Server behind a firewall to minimize malicious traffic
Uploaded documents stored in binary format in MySQL tables

8. Customer Requirements
Simple, easy to use interfaces for all user classes
Professional, trustworthy appearance
Several methods for contacting the service and providing feedback add to trustworthiness
Multilingual support for all three interfaces

9. Database Design

10. Database Design

11. GUI Design Professional Look and Feel with CSS
Lack of images greatly decreases download time

12. Session Design

13. Session Design URL Rewriting or Cookies?

14. System Implementation ERD for 1st Prototype

15. System Implementation Protecting against SQL Injection Attacks
This login would allow
access to any invalid
user.
For security, the special
characters in the values
must be escaped.
Other injection attacks may force the system to display sensitive data.

16. System Implementation Form Validation
Important for data driven applications
Ensure uploaded files are of proper type
MIME type
Extension
Description
application/pdf
.pdf
Adobe Portable Document File
application/msword
.doc
Microsoft Word Document
application/rtf
.rtf
Rich Text Format
application/html
.htm or .html
Hyper Text Markup Language
text/plain
.txt
Plain text

17. 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

18. 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

19. 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)

20. Future Work
Secure Sockets Layer (SSL) Support to cater to corporations and small businesses
Extended user interfaces including translation support system
Professional web hosting or dedicated server
