Go and PostgreSQL: Database Integration for Beginners

Integrating a robust database is essential for building scalable backend applications. Go provides excellent database support, but understanding how to connect and interact with PostgreSQL efficiently requires a solid foundation. This text-only course guides you from the absolute basics of database connectivity in Go to writing secure, high-performance SQL queries. You will learn how to structure your database code, manage connection pools, and handle data safely. What you'll learn: 1. Understand the fundamentals of Go's database/sql package and driver ecosystems. 2. Connect Go applications securely to a PostgreSQL database. 3. Execute safe SQL queries using prepared statements to prevent SQL injection. 4. Manage database connection pooling and leverage Go Context for query timeouts. 5. Handle database transactions and scan query results into Go structs. 6. Apply modern best practices for database migrations and clean code architecture. The course begins with foundational database concepts and setup instructions before moving on to hands-on written tutorials. You will read through practical code examples that demonstrate real-world database operations, error handling, and performance optimization techniques. This course is designed for beginner Go developers who want to start working with relational databases; no prior database integration experience in Go is required.
