PostgreSQL Basics Training

training provides a strong foundation in PostgreSQL, a powerful open-source relational database system. You will learn how to install, configure, and manage PostgreSQL in a development environment. The course covers:

• Working with various data types

• Writing SQL queries

• Designing efficient database schemas

• Optimizing query performance

• Transaction and user management

• Implementing basic security policies

• Performing essential backup and restore operations

The course blends theoretical concepts with hands-on exercises, enabling you to apply what you've learned in real-world projects.
