Learning RDBMS: Why You Should Learn PostgreSQL in 2021?

It is undeniable that the world is going digital, and the demand for open-source database systems is on the rise. The main reason for their popularity is that they allow users to create systems based on their unique business needs and requirements.

PostgreSQL is arguably the most advanced open-source relational database management system. It supports both JSON and SQL. It is characterized by several great features that help database administrators to ensure data integrity, developers to build applications, and help data scientists and data analysts to manage their data irrespective of the data set size. Read on to find out why you should learn PostgreSQL.


It does multi-index queries

PostgreSQL runs multi-index queries, which is the key piece of functionality that enables the rest of the functionality discussed below. The multi-index queries functionality implies that PostgreSQL will use all the indexes if you are running a query, and the conditions have different columns with their own indexes. This way, you don’t need to create an index combining multiple different columns - you just need to do one on each, and PostgreSQL will do the rest. The only time you may need to do a multi-index column is when you want to enforce uniqueness.

Built-in custom data types

PostgreSQL comes with built-in custom data types, including XML, JSON, hstore, arrays, intervals, geometric, ranges, and UUID, among others. Each data type has its own set of rules and functionality.

PostgreSQL can connect with outside systems.

Not only does PostgreSQL connect with other PostgreSQL,  but it connects with other database systems as well. It is possible to run a query in PostgreSQL that will get data from outside sources.


You can use PostgreSQL to store geospatial data because it supports geographical objects. This feature allows for efficient management of geographical information systems and location-based services.

Great performance

PostgreSQL performance is unmatched. It provides tablespace, sophisticated locking mechanisms, partitioned tables, and various types of indices. It offers advanced cost-based query optimization, and you can run parallel queries. It is these features and others that make PostgreSQL deliver unmatched performance as a relational database management system.

Excellent security features

The security features are another reason why you should find PostgreSQL tutorials, resources and training online and start learning.  PostgreSQL’s security features set it above most database management systems. It extends full support for single-sign-on, data encryption, SSL, and allows you to manage roles, users, and more as the project necessitates. In addition to that, its locking mechanism is unmatched.


Did you know that PostgreSQL is compatible with all major languages and most platforms? And on top of that, PostgreSQL supports JSON and SQL, and you can link it with other databases.


PostgreSQL meets all international compliance standards like ANSI. You can also use it to create ACID and HIPAA compliant applications.


In a nutshell, PostgreSQL supports multiple languages, and you can use it to build and run dynamic applications across different platforms. It is a popular choice in top companies, and it is also popular with medium and small-sized businesses. Do you want to climb the ladder of success? Add PostgreSQL as a skill in your profile.
