The Best Online SQL Courses, Classes, and Training

If you’re thinking of starting a career in data science, data analytics, or any other data-related fields, you need to learn SQL. Structured Query Language, also known as SQL, is one of the most important technologies to become a technical expert in your chosen field, and taking an online SQL course is one of the fastest ways to get the advanced knowledge you need. 

In this article, you will find a list of the best online SQL courses. First, you will get a vivid picture of what SQL is and how you can use it in the world of data. You will also find details on what to look out for when choosing online SQL classes, as well as the benefits of pursuing certification in this field.

What Is SQL?

Structured Query Language is a programming language primarily used to organize and extract data in relational databases. Using SQL, a data expert can retrieve any information from a database management system for analysis, perform nested queries, and make data-driven decisions. Over the years, SQL has become the standard language for all database-related issues and programming resources. 

The most popular version of SQL used today is MySQL, an open-source tool used to manage the server-side data of web applications. SQL servers are used for backend data storage by major tech companies across the globe. Apart from retrieving data, professionals can use SQL to execute queries, create new databases, and update database records.

Questions to Ask Yourself Before Attending an Online SQL Course

SQL Course Certificates vs Certifications

SQL certificates are given to students after they complete their course in SQL. They are given out by the course provider as proof that the student took the course and completed all the required classes. 

The best SQL certifications demonstrate that the student has mastered a specific aspect of this language. They are only awarded after passing an exam. Certifications are issued by the same companies that created the technologies covered in the exam or by neutral, standard-setting institutions. 

Importance of SQL Certifications

An SQL certification gives you a significant resume boost, increases your earning potential, and opens the door to new job opportunities. Currently, the best SQL certifications are offered by Microsoft, Azure, Oracle, and IBM. These companies provide different types of certification that can be more generic or specific in nature. Choose one appropriate to your level of expertise and in line with your career goals. 

Online SQL Classes, Training, or Courses: Which Is the Right Option?

Courses, classes, and training are similar terms that are frequently used in the education industry. Even though they are often used interchangeably, there are slight differences between them.

An SQL course is a program composed of several classes, each addressing different aspects of a particular subject matter. A course can last anywhere from a few days to several months. Classes, by contrast, are shorter and usually one-off lessons that focus on a specific subject or skill. 

Finally, training is a hands-on method of teaching based on a learning-by-doing approach. For example, an instructor may give instructions about an assignment and ask a student to put these theories into practice through coding challenges or real-world projects.

Classes are ideal for professionals who already understand SQL but are trying to upgrade their knowledge about a specific aspect of SQL. Courses are great if you want a more in-depth knowledge of SQL since they are more comprehensive. Training is for those who already have theoretical knowledge of SQL and are looking for hands-on practice. 

How to Choose the Right Online SQL Course, Class, or Training Program

Not every online SQL course is created equally. Since there are so many online SQL classes, research key aspects of each course before finalizing your decision. If you are not sure where to start, we’ve compiled a short list of some of the most important aspects to research before enrolling in an online SQL course below.

Course Syllabus 

What will you learn during the online SQL course? This is the first thing you should find out when you’re looking for the ideal program. Make sure the content of the SQL syllabus is relevant for beginners. This will prevent you from enrolling in a more advanced program which can be detrimental to your learning experience. 

When it comes to learning SQL, some of the topics you want to see in the curriculum are SQL coding, debugging, relational database, single table queries, database development with SQL, MySQL, data modeling, data visualization, Tableau, PostgreSQL, and Oracle database. 

Difficulty Level 

If you have never used SQL or any other database programming language, you must go for a beginner course. If you have already mastered the fundamental concepts, you should enroll in an intermediate program, while those with a firm understanding of this technology should take an advanced class. 

Be honest with your level of technical expertise when selecting a program. If you’re just starting in the field but choose a program designed for experts, you won’t learn the skills you need, and you will probably end up dropping out before completing the course.

Timeline and Flexibility 

Courses should not be based on rigid timelines. When picking an SQL course, go for one that allows you to focus on your job or other important activities in your life. You should not have to quit your job in order to earn that shareable certificate to upgrade your resume. 

To this end, you should enroll in a self-paced SQL course. This format will give you the freedom to decide when and how long to study. You can even stop learning in the middle of a class and resume in a few days’ time.

Cost

Every online SQL course comes with a different price point. When researching SQL classes, ensure that you look into the SQL training cost associated with the program. The cost will range drastically based on the course provider, university, and type of program on offer. Some programs are absolutely free. Continue your search until you find a course that fits your budget.

Instructor

Every online SQL course also comes with a different instructor or professor. Every professor has a different teaching style, and every student has a different learning style. Keeping this in mind, research the instructor and read student reviews. This will give you insight as to whether or not the instructor curates a comprehensive class that matches your needs and learning style.

Why You Should Take Online SQL Courses or Classes

Online SQL classes allow you to expand your knowledge base and learn everything you need to know about a specific aspect of SQL from the comfort of your home. In a matter of weeks or months, you can become a database administrator, data scientist, or business analyst.

SQL is currently the go-to programming language for data experts across the globe. Getting SQL skills gives you an edge in the job market and puts you ahead of your peers. If you are considering a data-related career, then taking an SQL course, class, or training is the way to go.
