Should You Learn SQL in 2022?

If you're looking for a programming language that will still be in high demand in 2022, SQL is a great choice. This powerful database management language has been around for decades and shows no signs of disappearing anytime soon. In fact, SQL is currently enjoying a resurgence in popularity thanks to its versatility and usefulness in managing large amounts of data.

SQL is the language of databases. And if you want to get into data science or database administrator, then you need to know how to use it well. This is because SQL will be the most used database technology for many years to come. So even if you don't end up using SQL in your day-to-day job, it's still important as a skill that employers look for when they are looking to hire data scientists.

What is SQL & Why is SQL important?

SQL is a standard database query language. SQL stands for Structured Query Language. SQL is used to communicate with databases.

SQL is the most popular data query language, database language, data analysis language, data manipulation language and data reporting language. It's also the most popular data modeling language.

Does SQL help my career as a data scientist?

The short answer is yes, but there are some caveats.

It’s used to query data and create databases across a wide variety of industries. SQL has become the most popular language for data scientists because it’s flexible and easy to use, so it can be applied across a multitude of fields.

If you want to work in machine learning or AI, then it's a sure bet that your employer will expect you to know at least some SQL (and perhaps Python too). If you're looking into jobs with large companies like Google or Apple, then it's also likely that they'll have their own internal database systems written in SQL as well – which means learning how these companies manipulate their data could give you an edge over other candidates!

Types of SQL queries for Data Science

You can use SQL queries for all of the following:

● Data science

● Data visualization

● Data analysis

● Data manipulation

● Data mining.

In addition to these, you can also use it for other purposes like data cleaning and wrangling, as well as integration with other databases.

SQL will be the most used database technology for years to come

The SQL language is standardized and used by all database vendors, big data platforms, data science platforms and analytics platforms. All of these tools use SQL to access their respective data sources.

As a result: if you know how to program in SQL you can easily interact with any tool that supports that language.

Should you get a Certification?

There are numerous benefits of a SQL certification. A SQL certification is an industry standard that employers look for when hiring. If you have a SQL certification, then it will help you market yourself as someone who has the knowledge and skills needed to be a successful data scientist. Additionally, having a SQL certification on your resume will make it easier to find employment because recruiters know that they can trust that person’s skill level and knowledge in this area. The final benefit of obtaining a Certification is that it helps build your skills as well as add new ones to your portfolio!
