In today’s world, it is crucial to be able to quickly adapt to new techs and inventions. At the moment, a lot of people tend to choose communication on social media over real-life communication. It is important to understand that there are alternative programming languages, such as SQL, and it is equally important to understand how they work and why you should choose them.
What is SQL?
In our society, such a term as SQL is increasingly appearing. It stands for Structured Query Language – a structured query language that was developed to work with a database, namely, to receive/add/modify data, be able to process large amounts of information, and quickly receive structured and grouped information.
SQL is used to query, insert, update and modify data. You can think of SQL as a means of communication between the user and the DBMS (Database Management System). Simply put, SQL is the programming language with which we access our database.
Every dedicated web developer must know SQL. Although it was created in the 70s, it is still very popular at the moment. Moreover, it would be hard to create something serious without it. The majority of the full-stack frameworks function with SQL. For that reason, it is important to deal with real SQL sooner or later.
Basic SQL Terminology
Since SQL is needed as a data organization, here are the basic terms used by programmers and analysts:
- Data – structured information.
- A database is a collection of data defined by the subject area. To put it simply: a set of tables
- A table is a way of storing information in a relational database (the smallest unit of measure in a database). A table is simply called a relationship in a database.
- DBMS – database management system: a program that allows you to perform various actions with databases.
- Business rules are formal rules that are considered when designing a database.
Reasons to Choose Studying SQL in College
Here are the main reasons for learning this particular programming language in college:
- The popularity of the programming language
While modern frameworks try to eliminate the need to use and learn SQL by offering ORMs, SQL specialists are more in demand than ever.
- Ability to manage data
Although a SQL developer is technically a “programmer”, you cannot write “programs” in SQL. All you can do is access and manage data.
- SQL is a strong enough programming language
The language is not only beautiful and elegant but has tremendous power. It allows you to formulate almost any analytical query to data.
Due to the lack of specialists in this field, the salary will always be decent.
- Ease of learning
The main difference between SQL and most languages is that it has a query-based structure. In fact, it provides users with the tools they need to conveniently manage the database.
- SQL is the way to always hang in Excel
Anyone who has worked with calculation knows that working in Excel with data larger than 50 MB is a game with fate, and using a function with this data size is a guaranteed restart of the application. In these situations, even the simplest relational database like SQLite will do well with a dozen gigabytes of data in a single file.
- High performance
SQL has high performance, which gives it a significant advantage over others.
- Programming language safety
In-place encryption allows you to perform cryptographic operations on sensitive data without moving it outside the database, so SQL is as secure as possible.
This is an important skill even for people who are not related to programming because even one-page users who only collect applications must store these applications somewhere. And the easiest way to do this is in databases.
It doesn’t matter if you want to work in data science, machine learning, database management, data analysis, and more, SQL is a common skill that is in high demand in the job market.

How to Learn SQL?
You can learn SQL from books or specialized courses. Many beginners stop learning after they have learned to program in a short amount of time. The basic concepts and syntax are relatively easy to learn and after that, you might think you already know everything. However, this is not so, the main thing in learning is practice. Solve problems and create your own databases. Once you understand something about the language – even if it makes you dizzy – start writing programs in it. It is sometimes difficult to find ideas for programs. It’s okay, you don’t have to come up with your idea at the very beginning. Later, using SQL, you can even do your homework using the same algorithm or geometry.
Who Needs SQL?
● SQL, as a simple and easy-to-learn language, is actively used today:
● developers to provide application functionality;
● testers in manual and automated testing;
● analysts to analyze and transform data;
● administrators to maintain a healthy environment. Also, if you learn SQL in a college or university, you can ask for help. There are companies that are engaged in SQL assignment help and are always happy to help you. SQL is everywhere where data storage and processing work is concerned, from machine learning engineers to financial professionals, web developers or data visualization experts, and even journalists. This is an important skill, mastering which you can build a career and even determine your position in life in the future. These were 10 reasons why you should choose SQL for your college studies. If you are good at computers, enjoy data management and analysis, and are looking for a new job, then learning SQL might be the perfect place to start. SQL, or Structured Query Language, is a programming language to learn. Start by getting familiar with the programming language, learn its syntax and purpose, and then choose it to study in college.
