ChromaDB Crash Course - Intro to Vector Databases

Master vector databases and embeddings in Python: map text to high-dimensional vectors, spin up a local ChromaDB, run end-to-end CRUD on collections and points, search by meaning, and persist your database to disk. We cover Sentence Transformers (local auto-embedding), OpenAI embeddings, and best practices for semantic search and RAG pipelines.
