Let’s take a peek into TripleTen's SQL course to learn about its benefits and the many possibilities it opens to future tech specialists.
Why should I learn SQL?
SQL stands for Structured Query Language. It's a computer languageData Analytics 101: All You Need to Know about SQL used to manage and manipulate relational databases.
You don't write programs in SQL, but you use it to store, retrieve, update, and delete data from databases.
Here's an example: Imagine you're a dean at an Ivy League university. You're tasked with looking into the records of all undergrads due to graduate in 2024 and providing information to the school so that they can plan for the upcoming academic year. Not all current undergrads will proceed to grad school, of course, but the university needs to consider its capacity. So, you have to check how many will likely choose to advance to the next level. Why not start by figuring out the number of students with a GPA of 4.5?
What if there are over 7,000 records on the current students list? Managing them one by one isn't very feasible. It’s not only time-consuming but has a high risk of human error. Thankfully, your assistants are skill-packed with SQL, so they retrieve this information in just two minutes.
Like the Ivy League, tech is fully packed with data, which should be stored in structured databases to be operational. Consider that website you like to order electronics from. Does it not contain a massive database of products? You'll find datasets in nearly every field you look at. That's why SQL is an essential skill in tech.
How can I learn SQL?
Once you’ve registered and received access to the study platform, it's easy to sort out the fundamentals of SQL through practical and comprehensive examples. TripleTen explains technical and abstract concepts through visual analogies and storytelling. Thanks to the interactive platform, you'll train your newly acquired skills as you learn.

What’s next: career paths for specialists with SQL skills
Once you feel comfortable with SQL, you can begin your straight-to-the-stars journeyLearn SQL: The Essential Skill for Data Scientists and Analysts to a tech career. Here are a few paths to consider, given your new skill.
Databases are essential parts of any application. As a software engineer, you'll need to understand how to model data, create tables, and define relationships. Identifying and understanding database architecture is part of your engineering job, and SQL is the tool for the job. With it, you'll design databases that meet the software application requirements and optimize data storage and retrieval. It's widely used in database management systems (DBMS) like MySQL, Oracle, Microsoft SQL Server, PostgreSQL, and SQLite.
Business intelligence analytics
BI analysts are professionals who extract valuable business insights from company data. They deal with loads of information, structure it, and analyze it. Analysts use SQL to write queries that retrieve specific data from databases. They use SQL's SELECT statement to filter data based on conditions such as specific dates, customer segments, or product categories. SQL functions like SUM, COUNT, AVG, and GROUP BY allow analysts to aggregate and summarize data. In turn, they use these to calculate metrics, such as total sales, average customer satisfaction scores, and monthly revenue.
SQL is arguably one of the most straightforward tools that a data scientist handles — any basic interaction with data starts with it. Even advanced prompts are executed with the help of SQL in data science. These professionals use SQL to perform exploratory data analysis (EDA) by writing queries to identify patterns, correlations, and anomalies. They filter, sort, and group data to better understand the dataset and generate hypotheses for further analysis.
SQL is as simple as writing math equations. If you understand this language, mastering other tools and hard skills required to begin your fantastic professional adventure in tech is as easy as pie. Try it today and advance your professional life with TripleTen in less than a year!
