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.

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:
Being an intermediate-level class, you may have a hard time keeping up if you’re just getting acquainted. However, if you have the prerequisite knowledge, it’s an excellent course for SQL server versatility across all significant versions.
