What Is SQL?

SQL or Structured Query Language is a versatile programming language used to communicate with databases. It enables users to efficiently store, manipulate, and retrieve data from relational databases – which are widely used across various industries. SQL Technologies Are More Common Than You Think!

Databases are organized into tables consisting of columns and rows. For instance, in a bookshop database, the books table would store books’ attributes (like ID number, title, author, and price) as rows. The sales table would include order ID numbers, dates, amounts, and references to other tables that store information on salespeople and stores.

But efficient storage isn't enough; data must also be retrieved effectively. This is where SQL shines. SQL provides a standard language for combining information from multiple tables. Tables are connected based on predefined relationships; this allows users to connect and analyze data from multiple tables and generate meaningful reports.

Furthermore, SQL facilitates the creation and maintenance of databases, making it an essential skill for data professionals. Here’s why SQL Is the Perfect Database Language.

You can read about the history of SQL in the article How It All Began by Agnieszka Kozubek-Krycuń. SQL is over 50 years old and it’s not going anywhere!

SQL's applications extend beyond relational databases. It’s employed in distributed data processing technologies and even integrated into popular spreadsheet applications like Excel and Google Sheets.

Despite its power, SQL remains beginner-friendly, making it accessible to users at various skill levels. It’s also a very good career choice.

A Well-Crafted SQL Practice Course

Our new SQL Practice: University course is the perfect stepping stone for SQL beginners who have grasped the basics and are ready to dive deeper. This course is built around hands-on practice and real-life database examples. We strongly believe that the best way to master SQL is through continuous application and practice.

The exercises are based on a fictional university database. You'll have the opportunity to interact with tables that contain details about students, lecturers, and various courses.

This interactive course isn't just about learning SQL commands; it's about writing SQL queries to perform data analysis and draw meaningful insights. It offers the experience of working on tasks similar to what you’d do in real life: determining the curriculum for a specific degree, tracking courses attended by a student, and listing the courses taught by a given lecturer.

To ensure comprehensive learning, our course is divided into six core sections, each focusing on an integral aspect of SQL. With a total of 156 hands-on exercises, this course offers plenty of opportunities to practice major SQL concepts. Each topic is given one section:

1. Selecting from one table: This section is all about using SELECT and WHERE to extract and filter data from a single table. You’ll get 33 exercises to practice these commands until they become second nature.
2. JOIN: Here, you'll delve into one of SQL's most powerful features—joining tables. With 31 practical exercises, you’ll gain expertise in using various types of JOINs to connect multiple tables and extract comprehensive data.
3. ORDER BY: Organizing and sorting data is a crucial aspect of SQL. This section comprises 22 exercises that help you master the use of ORDER BY to sort query results.
4. GROUP BY: This section is designed to test and enhance your understanding of SQL's grouping feature. It contains 24 exercises that offer hands-on practice using aggregate functions and the GROUP BY command to group relevant data together.
5. Other SQL Features: To round off your SQL skills, this module focuses on other key SQL features like subqueries and set operations. You'll also learn to work with NULLs and practice writing correlated subqueries. The 29 exercises will strengthen your overall SQL understanding.
6. Advanced queries: This is where you put everything together! With the knowledge gained from the previous sections, you will tackle more complex SQL queries. This is your chance to write advanced SQL queries using SELECT, WHERE, different kinds of JOINs, GROUP BY, HAVING, ORDER BY, set operators, and subqueries.

Each of these sections begins with a quick review of the necessary SQL syntax, so you’ll never feel lost or overwhelmed. Each review acts as a catalyst that aids smooth learning and recall.

How is the LearnSQL.com course different from others? First of all, it is fully interactive. In each exercise, you will write a real SQL query and see it run. You don't need to install or configure anything; everything happens in your browser. It doesn't get any easier.
