A glucose and insulin simulator, AIDA on-line, was completed to fulfill a senior design project and is available for educational purposes through the World Wide Web 0. Designed to be accessible and usable by anyone who desires to learn more about diabetes, AIDA on-line is available through The Shodor Education Foundation at http://www.shodor.org/aida/.The code for the WWW version was written in Perl and relies heavily on previously completed work on the AIDA glucose-insulin simulator. AIDA on-line allows the user to make modifications in diet and insulin regimen for 40 different pre-programmed "patients" or to create a patient with custom-designed specifications. Multiple simulations can be run in order to compare the results of changes in diet and/or insulin regimen. The results of two different simulations can be displayed on the same graph. INTRODUCTIONThe increasing popularity of the Internet and advances in technology have made it possible to implement interactive models on the WWW. AIDA on-line is an educational simulator that was designed to assist diabetics, students, and other interested parties in obtaining a better understanding of how insulin and glucose interact within the body (Figure 1).

Background. AIDA is a widely available downloadable educational simulator of glucose-insulin interaction in diabetes. Methods. A web-based version of AIDA was developed that utilises a server-based architecture with HTML FORM commands to submit numerical data from a web-browser client to a remote web server. AIDA online, located on a remote server, passes the received data through Perl scripts which interactively produce 24 hr insulin and glucose simulations. Results. AIDA online allows users to modify the insulin regimen and diet of 40 different prestored “virtual diabetic patients” on the internet or create new “patients” with user-generated regimens. Multiple simulations can be run, with graphical results viewed via a standard web-browser window. To date, over 637,500 diabetes simulations have been run at AIDA online, from all over the world. Conclusions. AIDA online's functionality is similar to the downloadable AIDA program, but the mode of implementation and usage is different. An advantage to utilising a server-based application is the flexibility that can be offered. New modules can be added quickly to the online simulator. This has facilitated the development of refinements to AIDA online, which have instantaneously become available around the world, with no further local downloads or installations being required.
