Vector Database
Definition
A specialised database designed to store and search high-dimensional vectors (embeddings). Vector databases enable semantic search — finding content by meaning rather than exact keyword matches. Popular examples include Pinecone, Weaviate, and ChromaDB.
In Plain English
A special database that understands meaning. Instead of searching for the exact word "car," a vector database can find documents about "automobile," "vehicle," or "driving" because it understands they're related concepts.
