Vector Database Fundamentals with ChromaDB

Modern AI applications rely on semantic search and rapid data retrieval to deliver accurate, context-aware answers. Understanding vector databases is the key to unlocking these capabilities, allowing you to store and query high-dimensional data efficiently. This text-based course guides you through the foundational concepts of vector databases and hands-on implementation using ChromaDB. You will transition from understanding core mathematical representations to writing clean Python code that manages embeddings, performs similarity searches, and connects to larger AI workflows. What you'll learn: - Understand the core concepts of vector embeddings, high-dimensional spaces, and distance metrics - Configure and initialize ChromaDB locally for development and testing - Create, update, and manage collections of vector embeddings - Apply metadata filtering to narrow down search results and improve query accuracy - Implement semantic search and basic retrieval-augmented generation patterns - Practice querying vector data through clear, step-by-step written code examples The journey begins with key definitions and architectural concepts before moving into practical, written Python implementations using ChromaDB. You will explore real-world patterns like semantic search and data filtering through structured text explanations and code snippets. This course is designed for beginner developers, data enthusiasts, and aspiring AI engineers who want to learn vector databases from scratch without any complex prerequisites.
