The Best PostgreSQL online courses and tutorials for beginners to learn PostgreSQL in 2020.

PostgreSQL is the world’s most advanced open-source relational database. It has a strong reputation for its reliability, data integrity, and robustness. Because of this, PostgreSQL is one of the most popular and widely used database systems in the world. Companies that use PostgreSQL include Apple, Cisco, Spotify, Fujitsu, Skype, Netflix, and IMDb.

PostgreSQL is arguably the most advance and powerful opensource enterprise-class relational database system. It is the object-relational database system and provides the most standard compliant system for the Database designers. It provides the complete support for reliable transactions that are (ACID compliant) where ACID stands for Atomicity, Consistency, Isolation, and Durability.

Its advanced underlying technology makes it extremely powerful and programmable. Support for concurrency is one of its key features. It is one of the most important technology you will learn and will greatly affect the way you work with Databases. It is the ultimate RDBM system that will allow you to create complex web apps that work flawlessly even for a very large number of users.

PostgreSQL is the fastest growing RDBMS and with a large and thriving community, it is a great asset to learn this amazing technology.
