Learn PostgreSQL with online courses and programs

Businesses can benefit from specialists who understand how to manage databases and keep them running efficiently without sacrificing security. Learn about the PostgreSQL database and how it works with edX courses.

What is PostgreSQL?

PostgreSQL is an open-source, object-relational database system known for its robust features, smooth performance, and reliability.1 There are many PostgreSQL data types, like numeric, character, boolean, and arrays, and it complies with ACID features — it offers high atomicity, consistency, isolation, and durability. It also comes with enterprise-grade functionality and scalability, which is why it can easily be deployed in a distributed architecture and can handle large volumes of data.2

Developers can use PostgreSQL to quickly build applications, safeguard data integrity, and maintain fault tolerance.3 Plus, it’s compatible with many programming and coding languages like Ruby, JavaScript, C/C++, and Python, which lets developers work with databases without any system conflicts.

How to use PostgreSQL

The core benefit of PostgreSQL is that it’s less prone to corruption and supports large datasets quite easily. For example, financial institutions may use PostgreSQL to store customer data and analyze their transactions safely. They can also identify fraudulent activities and stop them before it causes any damage. Or a social media app may use PostgreSQL to manage its multiple datasets.

​​It also offers full support for database encryption, single sign-on, SSL, and user and role management. Its application is wide: You can manage large-scale databases, build custom apps or IoT apps, and perform other tasks related to data mining.

PostgreSQL tutorial curriculum

A PostgreSQL course curriculum varies depending on the level. Introductory courses may focus on how to query data from a single table, filter data, and join tables. You may then explore how to use set operations, construct the subquery, and aggregate multiple tables. More advanced modules may also cover topics like how to operate database tables, create a new table, and modify the current table structure.

Start building your knowledge of how to work with data and databases. edX offers a variety of educational opportunities for learners interested in studying these topics, as well as a host of other disciplines. A boot camp can provide flexible, hands-on learning for those who want to upskill quickly, while executive education courses are designed for busy professionals. You can also pursue a more comprehensive curriculum in a bachelor’s degree program in a field such as data science, or, for more advanced learners, a master’s degree program.
