Your website needs a database to manage all the customer and product information. A database stores website content in a structure that makes it easy to retrieve, organize, edit, and save data. It runs on a remote computer called a server. There are many different databases that are widely used, such as MySQL, SQL Server, PostgresSQL, and Oracle.
Your app will still contain frontend code, but it also has to be built using a language that a database can recognize. Some common backend languages are Ruby, PHP, Java, .Net, and Python. These programming languages often run on frameworks that simplify the web development process. Rails, for example, is a framework written in Ruby. The hence-named Ruby on Rails is a popular technology for building dynamic web apps that makes the process much faster.
With all of these parts working together correctly, customers can visit your website and search for the particular kind of snack they want to buy – perhaps they want to pull up a list of treats made especially for small puppies. When they type it into the search box (on the frontend), the application looks through all the product data stored in the database (backend), and returns the appropriate information in the form of frontend code that the browser displays as the user’s requested list.
