PostgreSQL Database Management with SQLAlchemy

Managing relational databases manually can lead to complex, error-prone SQL scripts that are difficult to maintain. By combining the power of PostgreSQL with SQLAlchemy, you can interact with your database using clean, Pythonic code that scales seamlessly. This course guides you through the foundational concepts of database design and object-relational mapping, helping you transition from writing raw SQL to building structured database layers for Python applications. You will start with the essential terminology, understanding how relational databases organize data and how SQLAlchemy bridges the gap between Python classes and database tables. As you progress through the written lessons, you will learn to configure secure connections, design robust schemas, write efficient queries, and handle data migrations safely. What you'll learn: Understand core relational database concepts and PostgreSQL fundamentals; Connect Python applications to PostgreSQL securely using SQLAlchemy; Design database schemas using modern declarative mapping and type hints; Perform CRUD operations using both the ORM and SQLAlchemy Core; Manage database schema changes safely using Alembic migrations; Optimize query performance and handle database transactions. The course starts with basic installation and connection setups before moving into hands-on schema design, query building, and migration management. This course is designed for beginning Python developers, database novices, and web developers looking to add database management to their skill set, with no prior SQL or database experience required. Start reading today to build cleaner, more maintainable database applications.
