Requirements
- Basic SQL Knowledge: Familiarity with writing simple database queries (such as standard SELECT, WHERE, and JOIN statements) is helpful but not mandatory.
- Fundamental Python Skills: A basic understanding of Python syntax will help you comfortably follow along during the hands-on AI integration and LangChain labs.
- No Prior AI or Vector Experience Required: We teach the math and mechanics behind high-dimensional embeddings, pgvector, and HNSW indexes completely from scratch.
- A Computer (Windows, Mac, or Linux): You will need a standard laptop or desktop computer to install Docker or PostgreSQL and build your local development environment.
Description
Master the database engine powering the modern AI revolution.
Every major LLM application requires a reliable, blazing-fast backend to store, filter, and search high-dimensional embeddings. While many developers scramble to adopt complex, standalone vector databases, industry leaders are turning to the most trusted relational database on earth: PostgreSQL.
This course is a comprehensive blueprint for building production-grade, AI-native backends using PostgreSQL and pgvector. Whether you are starting from scratch with relational database fundamentals or you are a seasoned performance engineer looking to master advanced vector geometry, this course bridges the gap between traditional relational database management systems (RDBMS) and modern AI infrastructure.

Production RAG Architectures: Build complete Retrieval-Augmented Generation loops from scratch. Master document chunking pipelines and seamlessly integrate Postgres with LangChain and LlamaIndex.
The Hybrid Search Edge: Combine traditional SQL relational filters (CTEs, Window Functions, JSONB data) with semantic vector search for precise context retrieval.
Enterprise Operations & Security: Lock down your data using Row-Level Security (RLS), manage massive datasets with table partitioning, and scale read-heavy AI workloads with replicas.
