Databases are a fundamental part of modern software development. In real-world applications, programs need to store, retrieve, and manage data efficiently. One of the most powerful open-source database systems used in production environments is PostgreSQL.
In this course, you will learn how to connect Python applications with PostgreSQL and build database-driven applications step by step. Instead of only focusing on theory, this course emphasises practical learning through real coding examples. You will learn how Python programs communicate with a PostgreSQL database and how to perform common database operations directly from your Python code.
We will start by setting up PostgreSQL and creating a database. Then you will learn how to connect Python to PostgreSQL using a database driver and execute SQL queries from your Python programs.
You will also learn how to perform essential database operations such as:
- inserting data
- retrieving records
- updating existing data
- deleting records
By the end of this course, you will build a complete database-driven application using Python and PostgreSQL, helping you understand how backend applications manage data in real-world systems.
What You Will Learn:
- Connect Python applications to PostgreSQL databases
- Install and configure PostgreSQL and pgAdmin
- Execute SQL queries from Python programs
- Insert, retrieve, update, and delete database records
- Work with real database tables in Python applications
- Build a complete database-driven application using Python and PostgreSQL
