➊ Language
⬘ Applications are developed using a programming language like Java, C#, Python, Go, JavaScript, etc.
⬗ The application fetches data from a database using SQL or some similar language.
⬙ The data used in communication can be in XML, JSON, HTML, etc. format.

⬗ The application fetches data from a database using SQL or some similar language.

A back-end developer should thus be skilled in multiple languages.
But how to choose that? Here's how:
But how to choose that? Here's how:
➤ Popular language options for back-end are
❯ Java
❯ C#
❯ PHP
❯ Python
❯ JavaScript
❯ Golang
❯ Rust
❯ Ruby
❯ C++
(more)
❯ Java
❯ C#
❯ PHP
❯ Python
❯ JavaScript
❯ Golang
❯ Rust
❯ Ruby
❯ C++
(more)
Each of these languages may have different roadmaps. But, as a back-end developer, your goals should be learning:
❍ Language syntax
❍ Making and managing connections
❍ Intercepting the request and forming a response
❍ Asynchronous programming
❍ Error handling

➋ Data Structures and Algorithms (DSA)
A back-end developer works on writing business logic.
❯ Practice writing simple to complex algorithms
❯ Understand which data structure will fit a use case
❯ Improve problem-solving skills

➌ Framework
Examples of popular frameworks on the basis of the language are:
➤ Java
❯ Spring
❯ Jakarta EE
➤ C#
❯ .NET
➤ PHP
❯ Laravel
➤ Python
❯ Django
➤ JavaScript
❯ Express.js
* It's a sample list

⬘ A framework is needed in the back end for rapid application development.
⬙ A framework performs repetitive, time-consuming, and behind-the-scenes jobs which are mostly error-prone.
⬙ A framework performs repetitive, time-consuming, and behind-the-scenes jobs which are mostly error-prone.
⬗ Learn to do these things through a framework:
❯ Manage client connections
❯ Handle and intercept the incoming request
❯ AuthN & AuthZ
❯ Validate the inputs
❯ Communication with other systems
❯ Database
❯ MQ
❯ Caching Server

➍ API
⬘ API stands for Application Programming Interface. It gives a blueprint of all the requests and responses that the system can handle.
⬙ APIs help in
❯ consistency
❯ easy to enhance
❯ decoupling of systems

⬗ Popular API options are:
❯ REST
❯ GraphQL
❯ gRPC
❯ SOAP (* a little outdated)
⬖ In addition, you should be aware of

➎ Database
⬘ The back-end application may communicate with a variety of databases
❯ Relational (like MySQL)
❯ NoSQL (like MongoDB, Cassandra)
⬙ This is a roadmap for SQL developers. You can apply it to other types of databases as well.

➏ Other integrations
A back-end application may integrate with
❯ An MQ (Message Queue)
❯ A CMS (Content Management System)
❯ Email/SMS/Payment Gateways
❯ Chat Servers
❯ Streaming Servers
❯ External APIs
* These are optional

🏁 Final Words
⬘ Back-end developers typically manage the brain part of the application.
⬗ The backend communicates with multiple systems the same way the brain communicates with different parts of the body using nerves.
⬙ Hope this roadmap will help you. Good luck.
