Vector Database
Definition
A specialized database designed to store and efficiently query high-dimensional vector embeddings.In-Depth Explanation
Vector databases use approximate nearest neighbor (ANN) algorithms to quickly find similar vectors among millions or billions of entries. They are essential infrastructure for RAG systems, recommendation engines, and semantic search. Popular options include Pinecone, Weaviate, and Milvus.
Real-World Example
A semantic search engine stores document embeddings in a vector database to find conceptually similar content.
