System Implementation ERD for 1st Prototype 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. 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 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 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 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) 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 Questions?
