Web Navigation Model
To visualize the data flow as it relates to the actual structure of the web site, the following Web Navigation Flow Diagrams were prepared. Figure 2 shows the pages available through the public web space to all users and potential users. Note that while an initial applicant can make an application without any sort of authentication, a user requesting an upgrade and all other user functions require the user to be authenticated prior to performing any of these actions.
The volunteer portion of the web site will be secured using the inherent access controls of the Apache web server. As such, no user authentication library calls are required, the processing flow is somewhat simplified.
