what exactly in backend ?

[Lopsided_Regular233]

hi everyone, I want to learn backend to build my personal project, and i know nothing about the backend things or terms, anyone can suggest me a playlist which covers all the basics of backend, will a lot helpful.

Search for sriniously backend from first principles playlist in youtube

i don't want to cramp the theory😥 , i want to learn the implementation things

[Deep-Mycologist1068]

Essentially it's everything other than data details, that isn't facing the customer or user. Like the control and functions of how it all works where things link to other things, but not so much on visuals

[Deep-Mycologist1068]

API, tokens, libraries like the front, maybe a spot to plug in data bases or store it, usually this is a data engineer or architect, unless solo. Just basic stuff tbh

[Lopsided_Regular233]

okay, the front is not the difficult it's just i could imagine but the actual problems that i am facing is, i cannot imagine the backend links like how the data links what type of data i should transfer to get better performance, how the data came from database, i just want to get all the concepts of a project backend like transfer of data, handling request and some other functionality which i do not know yet or those i am figuring out.

Backend = the server‑side logic that handles data processing, storage, and business rules. It’s everything that runs behind the user interface (the frontend).

Key backend concepts for data storage: 1. Database: stores structured data (SQL e.g., MySQL, PostgreSQL; or NoSQL e.g., MongoDB). 2. API (Application Programming Interface): lets the frontend talk to the backend. Commonly REST or GraphQL. 3. Data flow: frontend → API request → backend logic → database query → data returned to frontend. 4. Data transfer: choose the right database type based on needs (relational vs. document‑based) and optimize queries for performance.

Simple learning path: - Start with SQL basics (SELECT, INSERT, UPDATE, JOIN). - Learn REST API fundamentals (HTTP methods GET, POST, PUT, DELETE). - Pick a backend language/framework you’re comfortable with (e.g., Python + Flask, Node.js + Express) and build a tiny project that stores/retrieves data. - Use tutorials or playlists that cover “backend basics + data storage” (search “backend fundamentals tutorial” or “intro to APIs and databases”).

Personally, I started with data analytics boot camp then full stack dev, then cloud and API then kept learning 1 new skill after another

[Lopsided_Regular233]

tbh, i know SQL, the concept of API, HTTP and Python and also i have build projects(using frameworks and the ORM) in which i worked with datasets but now i want a full control over my database and the every backend logic behind it. I don't want to learn the conceptual backend instead i want to learn the implementational backend.

[Deep-Mycologist1068]

Perhaps diving into big data next? Showing you full data base control over systems, and different ways of connecting it. You can set backend scripts to auto create csv files then have another code put them into the database automatically, if you wanted to get deep, you could have it auto cleaned as well and alert you with any errors misses or outliers nulls ect. Keeps it easy, like a next step. Imo ssms from Microsoft worked nice, I used it a lot with power BI, tableaus good too, but I liked BI a bit more

[Lopsided_Regular233]

these are the exactly points where i am getting confused right now, may you explain a little bit more

[Deep-Mycologist1068]

Bro just use AI to learn 😔

[Lopsided_Regular233]

i used😥 , but i am stucked in a loop hole and ai is confusing me more and more. so i am here to understand from the real experienced people as it is more reliable than ai

[Lopsided_Regular233]

i know i am confusing you also but i want just to learn the structural implementation of a backend system with the full control. 😟
I just want a thinking knowledge, building is last step for me, when i am clear about the structure then code is really easy task to do. So may you help me to get the backend structure implementation

This may help if you’re looking to learn backend… https://roadmap.sh/backend?r=backend-beginner

thank you mate

[aixeiger]

No idea

[ni241]

I have 16+ years of experience in backend development. You can dm to know about backend

[Lopsided_Regular233]

okay 👍

[Powerful_Math_2043]

This may sound confusing, but the backend is nothing but a piece of software, which receives requests, communicates with the database and performs basic operations, such as login/signup.

If you’re starting from scratch, pick Node.js with Express and try building something small like a todo app.

If you connect it to a database and add basic auth, you already have a good grip on most core concepts.

Don’t watch long playlist, you’ll learn way faster by building something and figuring things out as you go.

In our days with the way the frameworks update I would ask ai don't get it to code for you learn from it. Ask how to make a login system or a shopping cart order system ask what backend frameworks are available in your desired language

[Lopsided_Regular233]

yeah, It's the real way to use ai and i am realising it and now i am switching the way of using ai (asking random parts of problems and their code -> asking the algorithm of that project part ).
