Web Navigation Model

The dataflow will be managed using a combination of HTML pages, Javascript functions within HTML, CGI scripts, embedded PERL within HTML, and some shell script and PERL script library functions.

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.

 User Interactions with the System

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.
