PostgreSQL is a popular relational database management system. This course offers many features—from fundamental commands to advanced functionalities within PostgreSQL. 

You will learn simple queries, data definition, and data manipulation through SQL. You’ll be taught how to work with complex data types, regular expressions, views, indexing, and stored procedures. You’ll also learn about transaction control, administration, security, replication, and performance tuning. Following that, you’ll gain insight into the methods for backup, restore, and recovery. You’ll then learn about upgrading and migration from legacy systems. There’s also a mini project and a thorough assessment to enhance your learning experience and confidence.

This course is an ideal choice for developers who want to upgrade their database management skills with hands-on experience. Starting from the basic concepts, this course is an excellent option for those who want to switch to the field of databases.
