PostgreSQL, colloquially known as Postgres, is an open-source object-relational database management system. More than that, it is optimized to run with SQL. As such, it adopted ‘SQL’ in its name. SQL stands for Structured Query Language, a programming language that assists users in compiling, modifying, and storing data.

PostgreSQL is exceptionally versatile for storing projects and files in database systems and utilizing add-ons for additional features. Chances are that if you or your company is using PostgreSQL databases, you have a fantastic amount of control over your data. Using PostgreSQL open-source databases allows for an advanced level of control, customization, and execution, regarding data files.

It was developed by a dedicated group of software experts, led by Michael Stonebraker at the University of California. It launched in 1996, and it uses the PostgreSQL License. 

Which Jobs Use PostgreSQL Skills?

Okay, so let’s say you have undergone PostgreSQL training and are eager to start a career using those new skills. Which real-world jobs use PostgreSQL? 

  • Database Administrators. Database admins are crucial employees at any number of businesses. Data admins find the most work where large swathes of data are gathered. Think of something like a college or multinational technology corporation. 

Data admins also have great earning potential: the Bureau of Labor Statistics reports the median salary is $93,750 per year. It’s a growing occupation and will see a reasonably quick uptick in job growth over the next 10 years.

  • Computer Network Architects. These masters of using data to build and maintain network connections should be intimately familiar with SQL and PostgreSQL. That’s because these experts need every asset possible to get the job done. Computer network architects use the Internet to create a robust and fully functioning database for both small and large companies. 

  • Data Scientist. Becoming a data scientist is a lot of hard work. However, it usually pays off handsomely. Data scientists record, observe and parse through large amounts of data to form hypotheses and arrive at conclusions. 

Since PostgreSQL is an integral part of effectively storing big data, knowing how to use it properly can seriously help your chances of executing a data scientist’s duties.

How long does it take to learn PostgreSQL?

Depending on your proficiency with SQL databases and your ability to pick up new skills, you should be able to feel a lot more comfortable with PostgreSQL in two to three weeks. 

Below are a few steps to follow to make the process a little more clear-cut.

1. PostgreSQL Tutorials 

Tutorials are great resources for any subject, including PostgreSQL. There is no shortage of fantastic walkthroughs, documentation, and other PostgreSQL tutorials out there. Exploring PostgreSQL tutorials allows you to learn the in-depth process alongside experts and see what it takes to learn the open source object-relational database management system.

2. Take PostgreSQL Courses

Taking online courses is a surefire way to learn nearly any subject from the comfort of your own home. Receiving adequate PostgreSQL training in this manner is just one of the best ways to master advanced levels of PostgreSQL. We’ll delve deeper into some of the best courses, including supplemental resources to give you a little boost. 

3. Enroll in a Coding Bootcamp

Coding bootcamps are unique, precisely tailored coding programs that teach you specific software development skills. There are numerous programs dealing in everything from JavaScript to UI/UX design. 

If you’re looking to learn PostgreSQL, enrolling in an intensive coding bootcamp can teach you all you need to know about open-source databases, as well as SQL. These fundamentals will enhance your knowledge to such a degree that you’ll pick up the basics in no time. Coding bootcamps can be an attractive alternative to a more generalized degree in computer science, too.

4. Practice, Practice, Practice

You can’t expect to learn PostgreSQL without a bit of practice. Once you peruse some resources, take online courses, or enroll in a coding bootcamp, ensure that you feel comfortable with the open-source database. 

Choose what you want to focus on. Since PostgreSQL can help in things like geospatial tech, why not see how to master those more advanced levels of operation? Try exploring PostGIS to discover how to store notable geographic location data easily, for example.

The Best Courses to Learn PostgreSQL

Taking online courses is a crucial step in your quest to learn PostgreSQL, and one of the best ways to enhance your knowledge of the open-source database tool. Let’s see which courses you need to check out for optimal learning.
