Backend development handle the ‘behind-the-scenes’ functionality of web applications. It’s code that connects the web to a database, manages user connections, and powers the web application itself. Backend development works in tandem with the front end to deliver the final product to the end user.
The back-end, or the “server-side”, is basically how the site works, updates and changes. This refers to everything the user can’t see in the browser, like database and servers. Usually people who work on the back-end are called programmers or developers. Back-end developers are mostly worried about things like security, structure and content management. They usually know and can use languages like HTML and CSS, but that’s definitely not their focus. Back-end developers, or at least back-end development, is required to create a dynamic site. A dynamic site is a site that’s constantly changing and updated in real-time. Most sites are dynamic sites, as opposed to static sites. Facebook, Google Maps and this blog are all considered dynamic sites. Blogs are dynamic sites, since their content is constantly changing and updating. A dynamic site requires a database to work properly. All information, like user profiles or images they’ve uploaded, or blog posts, are stored in the database. Web developers work with programming languages like PHP or .Net, since they need to work with something the database understands. The code they write communicates with the server and then tells the browser what to use from the database.
