Editing Multitier architecture (section)

===Web development usage===
In the [[web development]] field, three-tier is often used to refer to [[website]]s, commonly [[electronic commerce]] websites, which are built using three tiers:
# A front-end [[web server]] serving static content, and potentially some [[web cache|cached]] dynamic content. In web-based application, front end is the content rendered by the browser. The content may be static or generated dynamically.
# A middle dynamic content processing and generation level [[application server]]  (e.g., [[Symfony]], [[Spring Framework|Spring]], [[ASP.NET]], [[Django (web framework)|Django]], [[Ruby on Rails|Rails]], [[Node.js]]).
# A back-end [[database]] or [[data store]], comprising both data sets and the [[database management system]] software that manages and provides access to the data.
