Web development is the coding or programming that enables website functionality, per the owner's requirements. It mainly deals with the non-design aspect of building websites, which includes coding and writing markup. Web development ranges from creating plain text pages to complex web-based applications, social network applications and electronic business applications.
Just as with a traditional desktop application, web applications have varying levels of risk. A personal home page is much less risky than, for example, a stock trading web site. For some projects security, software bugs, etc. are major issues.
If time to market, or technical complexity is a concern, documentation, test planning, change control, requirements analysis, architectural description and formal design and construction practices can mitigate risk.
In simple terms a program residing on server and end user accessing it via web clients (web browsers) are known as web application. There is a thin line between websites and web application. Web technologies always have lot to offer for development. We see new tools and technologies added to web stack every year. Advantages of Web Application:-
Web development is quickening at an aggressive rate. Engaging and user-friendly UI is in demand. Web plays a major role in communication, media and news. Web applications are business policies implemented on the web with the use of business, user and data services.
Scalability is related to the load balancing between the servers, therefore, whenever, the load increases, additional servers can be added to balance it. Hence, before designing the application, make sure it works on a bunch of servers.
The website security are: unauthorized access to restricted parts of website, user data, database malfunctioning and so on. Some common security threats are, Cross-site scripting, Shell injection, Phishing, SQL injection, and so on.
In the era of smartphones, client-oriented web apps are highly in vogue. The presence of small UI elements makes a huge difference. If your web apps frustrate users, it becomes difficult to maintain customer loyalty.
Website speed plays a crucial role in the success of any website. Slow websites lead to failure. Performance issues can occur in the form of an unoptimized database, poorly written code, poor load distribution, troublesome third party services.
