WebSite vs Web Application

WEB APPLICATION:
An application that is delivered using Internet technology and meets one or more of the following conditions:
Utilizes a database (such as Oracle or SQL Server)
Is developed using an application development tool (such as Oracle Internet Developer Suite or Visual Studio)
Extracts data from multi-record files
Requires a constantly running server process (such as Newsgroups and Chatrooms)
Stores input data from data entry screens or web forms
Depending on its requirements, a web application may be an Internet Application or an Intranet Application.

WebSite vs Web Application:
Historically, a website is any site on the internet (whether simple or complex) in which visitors can go. Therefore, whether it's a static site (the visitor can only read information or research a topic,) or whether it's a dynamic site (such as an online e-commerce store that can be managed by the store owner online) it's considered a website. A web application is also considered a website. However, web applications are web-based software programs, often as powerful as software applications made for your home or business computer. For instance, many online e-commerce stores are web applications. They are software programs that run on the web and are accessed via the internet instead of running strictly on your PC
