Back-end, or the the server-side, is the non-visual side of a software application that stores the data. But what languages and programs make it possible to build back-end applications, store data, and deploy code? Let’s take a look at some of the most commonly used back-end tools by developers.
Back-end applications can be built in almost any modern language, such as Ruby, Java, PHP, Python, Scala, and Go. In addition to choosing a language, many back-end developers choose to use a web framework, which is a collection of code libraries aimed at letting developers focus on their specific needs for building an application.
Common web application frameworks:
Storing Data in a Database
Most back-end applications have some kind of persistence—some way to store data on the server in a database. There are a few families of databases, and in each family there are several choices.
Brief overview of two broad categories of databases:
RDBMSs (relational database management systems) that use SQL
Time to Deploy!
In order for your back-end application to work on the web, you need to deploy it—that is, you have to make sure that there’s a server running your code that allows it to be part of the public internet and available through a domain name.
Popular places to deploy code are:
The world of back-end development is vast and this is just the tip of the iceberg. Stay tuned, next we jump into algorithms.
