Would you like to build up your database management skills?
Data is all around us today. It powers everything from complex business solutions like demand forecasting to simple everyday tasks like creating to-do lists.
SQL is therefore not only important for business analysts but also if you’d simply like to gain problem-solving skills applicable to everyday life scenarios.
Without the proper SQL knowledge, it would be difficult to manage big data situations.
We would have to rely on traditional data processing techniques like manipulating Excel spreadsheets. This would require a ton of effort to even execute simple data processing tasks, and workflows would hog a lot of resources as a result.
Consequently, for efficient data analytics projects, it’s essential to learn SQL.
In this guide, we’ll be discussing the best SQL courses and certifications to take in 2021 for all-around database management expertise.
Let’s get started.
Don’t have a clue about anything SQL?
You’ll feel right at home with one of the best SQL courses online on how to query a database using SQL, which is one of the most highly sought-after skills, besides PostgreSQL.
Additionally, you’ll learn about:
- The various parts of basic SQL statements, and how you can use these to update a variety of databases you’ll come across.
- Getting started with PgAdmin and PostgreSQL, which are today’s most popular SQL tools no matter what line of data science work you end up in.
- Real-world problems and how you can query SQL to solve them. The practicality of this course, and the succinct yet clear explanation on otherwise complex topics, are excellent as well.
I feel that there could be a few more exercises around the PGAdmin to better reinforce the concepts. Nonetheless, it is still one of the best SQL courses on Udemy as the examples offer incredible insight into how to interact with databases using this GUI tool.
Are you intimidated by most MySQL courses?
Then this is one of the best SQL tutorials as it involves creating SQL models from real-world data without prior programming knowledge.
Some course highlights include:
- Learning how to ask your data questions on marketing analytics such as campaigns with high click-throughs, product abandonment, etc.
- Creating web apps through MySQL and NodeJS, enabling you to fit in a work setting with a focus on app development.
- I especially like how the instructor fuses his personality, and that of his companion, into breaking down complex topics in a lighthearted learning approach.
However, I find this may not be the best SQL course on Udemy if you’re pressed for time as the instructor often goes into detailed exercise reviews. That said, these bits of added information make learning more effective.
Most of the best SQL training online classes focus on web development, cutting out the non-technical business person who is more interested in SQL’s business applications. If that describes you, this is the course to take.
The class covers:
- Real-life data analytics featuring complex tables with millions of variables, which prepares you for actual situations in the real world.
- Lifetime access to bonus courses on advanced Microsoft Excel training, which will come in handy when you need to create tabular schema to facilitate data entry into your business’s relational database.
- A refreshing view into how to handle SQL joins for complex databases with countless tables and variables, making this one of the best SQL courses on Udemy.
Nevertheless, the Q&A section could be better as the instructor is sometimes unavailable to promptly handle queries. On the plus side, many of these questions have been previously answered in the Q&A.
Do you struggle with database normalization?
If so, this is among the best online SQL courses for handling a topic that has proven quite challenging for beginners.
This lesson entails:
- Advanced database normalization techniques for both PostgreSQL and MS SQL, thereby enabling you to better structure different kinds of data.
- Easy-to-learn strategies for making and cleaning complex joints, making this an excellent course for handling huge relational databases.
- Advanced SQL query techniques to enable you to draw from multiple conditions to draft a report. Some of these queries are commonly asked in interviews.
However, because the course stretches to cover both PostgreSQL and MS SQL, aggregations aren’t exhaustively covered to their full possibilities. On the plus side, this is the best SQL course on Udemy for value as it is a two-for-one course.
Would you like to apply SQL in data science?
Then this is one of the best SQL courses online for learning data science from a programming perspective.
Some course highlights include:
- Learning how to use SQL commands to filter and sort data. This enables you to better perform cleaning on large datasets.

- The final course assessment makes it one of the best SQL courses on Coursera for practicing.
The course could do with some graphic effects to highlight exact points in the presentation as the instructor is taking you through the data sets. Nonetheless, you can still follow through from the voiceovers.
Most businesses today rely on Excel spreadsheets to store data.
Consequently, this is one of the best SQL tutorials for learning how you can use both SQL and Microsoft Excel for data analysis.
You’ll also learn about:
- Using tableau software to visualize data and drive meaningful financial insights to guide business decisions.
- Multi-industry data analysis skills given that this is a 4-in-1 specialization course, making it the best SQL course on Coursera for all-around business prowess.
- Managing big data with MySQL to create business value from various information sources.
On the downside, because it is a 4-course program, it may take you up to 7 months to complete on an average 4 hour/week pace. On the bright side, you can sign up for the individual courses in the package according to your needs.
If you’re interested in SQL for professional data science certification, this offers the best SQL training online.
Course highlights include:
- A multi-programming approach, featuring the most popular programming languages for data science, namely SQL and Python.
- A Professional IBM certificate and a digital IBM badge, both of which prove your qualifications to potential employers.
- Hands-on labs in IBM Cloud, entailing tools like Juptery Lab, Github, and libraries like Matplotlib, Mumpy, and Pandas. This practicality makes this one of the best SQL courses on Coursera.
However, to get the professional certificate you’ll need to complete at least 9 courses in the specialization. The good news is that you can learn part-time for up to 12 months or go into full-time learning to finish in 3 months.
For a better understanding and analysis of big data via MySQL, this is one of the best online SQL courses to get you started.
Some course expectations encompass:

Unfortunately, this course focuses on an older version of Hive, i.e. Hive 0.11, so it may be a let-down if you’re keen on Hive 1.2.1. Nonetheless, Hive 0.11 remains one of the most stable versions of Hive for big data processing and is also still very effective for learning standard HiveQL.
Physical database design doesn’t get enough attention, yet it is still important because it significantly impacts performance.
If you’re keen on an SQL Server tutorial that factors in physical database design, this is one of the best online SQL courses to show you the ropes.
Here’s what this class teaches:
