My name is Samson, and I’m currently learning backend development.
When I started, one of the hardest things for me to understand was databases. I spent a lot of time on YouTube, but honestly, most tutorials left me more confused than before. Some were too fast, others skipped important steps, and I never really felt confident.
Everything started to change when I found Scrimba.
After completing their MySQL course, I finally understand how databases work and how they are used in real applications.

The Turning Point for Me
Before this course, SQL just looked like randomn commands I had to memorize.
But during the course, something clicked.
Instead of just copying code, I started understanding:
- Why we create tables
- How data is structured
- How backend systems actually use databases
That shift from confusion to understanding made a huge difference for me.
What I Learned
Tables, Rows, and Columns
At first, this sounded basic—but it’s everything.
Now I understand that a database is just structured data.
CRUD Operations (This Was Huge)
This is where things started feeling real.
Example I practiced:
INSERT INTO users (name, email)
VALUES ('Samson', 'samson@email.com');
SELECT * FROM users;
This is exactly how apps store and retrieve data.
Queries Finally Made Sense
Before, I didn’t understand what queries were doing.
Now I can read something like:
SELECT name FROM users WHERE id = 1;
And actually understand it.
Understanding Relationships
This part was challenging, but also very important.
I learned how tables connect using:
- Primary keys
- Foreign keys
This is what allows real-world systems to work, like:
- Users and their orders
- Posts and comments
What I Struggled With Before
To be honest:
- I didn’t understand how databases connect to backend code
- SQL felt like something to cram, not understand
- Tutorials didn’t explain the “why”
I used to think maybe backend wasn’t for me.
What Made Scrimba Different
What helped me most was:
- Interactive learning (not just watching)
- Clear explanations
- Practicing while learning
Instead of just watching, I was doing.
That made all the difference.
What I’m Learning Next
Right now, I’m moving into:
- Node.js
- Building APIs
- Connecting MySQL to backend systems
Final Thoughts
If you're struggling like I was, don’t give up.
Sometimes you just need the right learning approach.
Things will eventually click.
