WEB APP

Web application development is the process of building application programs that reside on remote servers and are delivered to the user’s device over the Internet. A web application (or web app) is application software that runs on a web server, unlike computer-based software programs that are run locally on the operating system (OS) of the device. Web applications are accessed by the user through a web browser with an active network connection. A web application does not need to be downloaded and is instead accessed through a network.

Web Apps are built with web technologies (HTML, CSS, JS), which stores (Database, Files) and manipulates data (CRUD), and is used by a team or single user to perform tasks over the internet. CRUD is a popular acronym and is at the heart of web app development. It stands for Create, Read, Update, and Delete.

A database such as MySQL or MongoDB can be used to store data in web application development. An end user can access a web application through a web browser such as Google Chrome, Safari, or Mozilla Firefox. A majority of web applications can be written in JavaScript, Cascading Style Sheets (CSS), and HTML5. Examples of commonly-used web applications include: web-mail, online retail sales, online banking, and online auctions.
