How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Appian with MySQL with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Where is MySQL used?
Keeping the Web World Spinning
- Imagine a world where your favorite meme-sharing site freezes like a deer in headlights. MySQL is the unsung hero keeping these social hubs buzzing without a glitch.
E-commerce Shopping Sprees
- From splurging on fuzzy socks to splashing out on tech gadgets, MySQL manages the swarm of transactions during your midnight shopping fiestas.
The Gamer's Save Point
- For every dungeon delver and space explorer, MySQL safeguards your precious progress. No dragon can torch or black hole can swallow your save files.
Silicon Valley's Pet Rock
- In the cutthroat startup playpen, MySQL is the trusty sidekick every tech whizkid leans on to hoard user data like a digital treasure trove.
MySQL Alternatives
PostgreSQL
Open-source, object-relational database system with a strong reputation for reliability, feature robustness, and performance. Well-suited for large-scale applications and complex queries.
SELECT * FROM users WHERE age > 30;
- Supports advanced data types and SQL compliance.
- Handles complex operations and multi-version concurrency control.
- Might have a steeper learning curve for new users.
MariaDB
A community-developed fork of MySQL intended to retain free status under the GNU GPL. MariaDB is compatible with MySQL commands, but it comes with additional storage engines and improvements.
INSERT INTO products (name, price) VALUES ('Gadget', 19.99);
- Drop-in replacement for MySQL with additional features.
- Continued open-source commitment.
- Potential compatibility issues with existing MySQL deployments.
SQLite
Self-contained, serverless, zero-configuration, and transactional SQL database engine, widely deployed for its simplicity. Ideal for embedded applications or simple web apps.
UPDATE accounts SET balance = balance - 100 WHERE id = 1;
- Lightweight, no need for setup or administration.
- Great for prototyping and small to medium-sized web apps.
- Not suitable for high-concurrency or write-intensive applications.
Quick Facts about MySQL
A Vintage Wine in the Tech World
Picture this: It's 1995, flannel shirts are in, and Michael Widenius (more affectionately known as 'Monty') decides to bless the tech world with MySQL. Like a fine wine that gets better with age, this open-source prodigy, named after Monty's daughter My, quickly fermented into the database darling we know today.
Version Leapfrogging!
Did MySQL just skip a grade? You bet! The tech wizards behind MySQL decided to jump from version 5.7 straight to 8.0 in 2018. Why? Because why not show off a little and make the leap to a more "mature" version number—it's not just for semantics; they packed in window functions, CTEs (common table expressions), and a whole lot more!
Storage Engine Swap Meet
If MySQL were a car, it'd win 'Pimp My Ride'. Originally strutting around with the default MyISAM storage engine—a cool but slightly outdated jacket—it switched to InnoDB in 2010 (version 5.5) for its main attire. Why? For the elegance of transactions, the robustness of row-level locking, and the sheer joy of referential integrity. Check out the snazzy upgrade:
ALTER TABLE my_table ENGINE=InnoDB;

Top 10 MySQL Related Tech
SQL Mastery
Ah, the bread and butter of database tech! Knowing SQL is like mastering the ancient runes that control the data-beasts. You've got to select, insert, update, and delete with grace and precision. It's all about those crafty queries that can make or break your application's mood... I mean, performance.PHP Serenade
Now, this might feel like a throwback to some, but PHP is like that '80s love ballad that never really went out of style for web development. It swoons over MySQL and they create beautiful data-driven symphonies together, assuming you don't hit any bum notes with your code.
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "my_db");
if ($mysqli->connect_error) {
die('Oops! ' . $mysqli->connect_error);
}
$result = $mysqli->query("SELECT joke FROM comedy_club");
?>
Python Cuddles
Snuggle up with Python for some serious MySQL action. It's the cozy sweater of programming languages: versatile, comfy, and snuggly fits any database interaction you need. Just import that sweet pymysql or SQLAlchemy and watch the magic unfold.
import pymysql.cursors
connection = pymysql.connect(host='localhost',
user='user',
password='passwd',
db='db',
charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)
try:
with connection.cursor() as cursor:
sql = "SELECT `id`, `password` FROM `users`"
cursor.execute(sql)
result = cursor.fetchall()
finally:
connection.close()
ORM Love Affair
Can't be bothered with SQL syntax? No problemo! ORM (Object-Relational Mapping) frameworks like ActiveRecord (Ruby on Rails), Hibernate (Java), and Django ORM (Python) will let you treat database interactions like a high school fling – no deep understanding necessary, just lots of enthusiasm.Node.js Flirtation
Dabble in the non-blocking romance of Node.js, where even your database calls feel like asynchronous love letters. Packages like Sequelize or the mysql module keep the conversation with your MySQL database flowing smoother than a Casanova.
const mysql = require('mysql');
const connection = mysql.createConnection({
host : 'localhost',
user : 'me',
password : 'secret',
database : 'my_db'
});
connection.connect();
connection.query('SELECT * FROM aliens WHERE planet = "Earth"', (err, results) => {
if (err) throw err;
console.log(results);
});
connection.end();
RESTful Romancing
Truly, a love story for the modern age. Expose your MySQL database to the world with RESTful APIs. Technologies like Express.js with Node.js or Spring Boot with Java enable you to set up endpoints so that even client-side JavaScript can whisper sweet nothings to your data.Dockerized Date Nights
Don't fancy setting up MySQL on your machine? Spin up a Docker container instead! It's like ordering from a fancy restaurant but for databases. Portable, consistent, and won't leave a mess on your server when you're done.
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag
Git Commitment
Think of Git as your relationship diary. Every change, every tweak, and every bug fix to your MySQL driven apps are recorded like poetic entries. Branch out, merge your efforts, and stay committed. Remember, great devs commit often!Cloud Connections
Elevate your MySQL experience by bringing your database to the cloud. AWS RDS, Google Cloud SQL, and Azure Database for MySQL are like dating apps for devs — find the perfect managed database service that matches your application's needs.Monitoring & Alerts
Keep an eagle eye on your MySQL with monitoring tools like Prometheus and Grafana or New Relic. It's like having a personal assistant who's always paranoid about performance issues, which in this case, is a good thing!
