A ‘Web Application Development’ is a business system or application delivered over the Web. It might be an internal expenses application used only within a company (intranet); a reseller purchasing application used with partners (extranet); or an online system available to members of the public like an eBay or a holiday cottage search site.
Web applications utilise the interactive nature of websites to provide customised and interactive technologies; they deliver a more sophisticated and interactive user experience than conventional websites.
Web applications are less likely to be built on top of third-party e-commerce or CMS platforms and are instead normally written from scratch. The fact that Web applications are bespoke software development projects essentially means that the sky’s the limit in terms of what they can be made to do.
If you have specialist requirements (such as a requirement for integration with another system) and you’d like your project to be Web-based, you’re probably going to need a Web application.
