Many sites and portals that we visit on a daily basis are in fact web applications. These are email resources, social media pages, search tools, online banking systems, online stores, online editors, games, and much more.
As mentioned, the key difference between web applications and websites is that they are not static data in the form of documents on the Internet, but executable programs. Web applications are client-server solutions that are stored on the server and run on the server and on the user’s computer or smartphone.
The back-end of the web application is the main part of the program where the calculations take place. They are performed based on the Internet requests of users sent through web browsers. Moreover, many clients can have access to the server side of web applications at the same time. Developers familiar with PHP, ASP, Perl, C / C ++, Java, Python, etc. technologies are involved in the development of the Back-end parts of web applications.
The client part of a web application (Front-end) is an interactive part of a program that is executed in a web browser on a user’s computer, smartphone or tablet. It implements the user interface of a web application and is loaded onto devices as dynamic web pages. Web applications run on any device and operating system that has an Internet browser. Developers who are familiar with React, Vue.js, Angular, JavaScript, HTML, CSS, Ajax and others technologies are attracted to develop the Front-end parts of web applications. Recently, the development of web applications in Java is very popular.
A web application database is a huge array of all kinds of information that a business needs. At the request of the user, the server side of the web application uses this data to process and provide it to the end client.
Thus, the development of web applications allows you to abandon the binding of a mobile or application program to any one platform – Windows, MacOS, Android or iOS. Web applications will work wherever there is a web browser and internet access.
