Cholesterol Metabolism Simluation HOME ALGORITHM APPLICATION ARCHITECTURE BACKGROUND GLOSSARY STATISTICS ABOUT CREDIT EVALUATION FORM HELPFUL LINKS	Architecture provides fundamental structure for the procedures. Methods and Procedures     In studying cholesterol for my project, my first procedure is to gather data and information about cholesterol metabolism. Three basic reuirements for using a model of cholesterol metabolism on a computer are algorithms, architecture, and application.    Receiving and inputting mathematical formulas into a program called, STELLA, is one first step. STELLA provides calculations on time and on how cholesterol metabolism works during a certain time. After obtaining a correct estimate based on probabilities, we then write a source code for a stand-alone program that is working on the computer without STELLA running. The code is written in Perl language that will work with HTML (hypertext markup language) very well.    a simulation-based program is saved in a Perl format and into a CGI (Common Gateway Interface) format also, to allow running the model on the web page communicating with the server.
