In this video tutorial, we dive deep into PostgreSQL, one of the most powerful open-source relational databases available. You’ll learn how to create and access databases using three essential tools: pgAdmin, psql, and DBeaver. We start by guiding you through the process of installing PostgreSQL and setting up your environment. From there, you’ll explore pgAdmin, the graphical interface that simplifies database management. We’ll demonstrate how to perform key tasks like creating databases, running queries, and managing users within the pgAdmin interface. Next, we shift our focus to psql, the command-line tool, to give you a hands-on approach to interacting with your databases. Finally, we introduce you to DBeaver, a powerful and flexible database management tool that supports multiple databases, including PostgreSQL. By the end of this tutorial, you’ll have a solid understanding of how to navigate and manage PostgreSQL databases using these tools, making it easier for you to build and maintain database-driven applications.
