Backend Development

  • Back-end code adds utility to everything the front-end designer creates.
  • The back end is a combination of a database and a software written in a server-side language, which are run on web servers, cloud-based servers, or a hybrid combination of both. A network’s server set-up can vary, with the server-side workload divided up between various machines (e.g., a server dedicated to housing the database).
  • This server-side application directly interacts with the database via an application programming interface (API), which pulls, saves, or changes data.
  • The data are returned and converted into front-end code a user interacts with: filling out a form, creating a profile, shopping online, etc.
  • In general, anything you see on a site is made possible by back-end code, which exists on, and is powered by, a server.

Responsibilities of the back end can include

  • Database creation, integration, and management—e.g., MySQL, SQLite, PostgreSQL, and MongoDB. SQLite is lightweight and fast, making it a very popular alternative to a larger MySQL driver.
  • Using back-end frameworks to build server-side software, like Express.js
  • Web Server technologies—e.g., J2EE, Apache, Nginx (popular for static content, like images, HTML or CSS files), and IIS
  • Cloud computing integration—e.g., public cloud providers like Amazon Web Services, or private cloud environments
  • Server-side programming languages—like Python, Perl, PHP, Ruby, and JavaScript, when implemented with the server-side development environment, Node.js
  • Operating systems: Linux- and Unix-like operating systems, MacOS X, Windows Server
  • Content management system (CMS) development, deployment, and maintenance
  • API integration
  • Security settings and hack prevents
  • Reporting—generating analytics and statistics like system reports of server load, number of visitors, geography of visitors, etc.
  • Backup and restore technologies for website’s files and DB.
