Communication Diagrams for Using a Connection Host

An 

Application Server

 can run on any computer with access to the Internet. Worth Data provides 

programming tools for creating Windows Application Servers, but you could also create your own that runs 
on other platforms (Linux, Apple, etc.).

A 

“Cloud” web-based application

 server is essentially a special website installed on a web server. 

Typically it would be created as a script, written in PHP or ASP or whatever language is your favorite. It 
uses the web server's database “backend” to store data collected by Terminals and to store information on 
how the Terminals should behave (what their data-collection routine is). This approach could be used to 
integrate portable terminal data collection with your existing web-based application.
