Current mainstream RAG implementations mostly use vector databases to perform dense retrieval over unstructured text, while their retrieval support for structured data sources such as tables and relational databases is relatively weak.

VerifiedVector databases, by converting text into high-dimensional vectors and building approximate nearest neighbor (ANN) indexes, form the core infrastructure of the RAG (retrieval-augmented generation) architecture.78% similarVerifiedIn scientific research scenarios, RAG is typically used in combination with vector databases such as Pinecone and Weaviate.77% similarVerifiedMainstream solutions for addressing the limited context window of large language models include vector database retrieval-augmented generation (RAG), summary compression, and external memory storage.76% similarUnverifiedFor RAG to work effectively, external data must have clear metadata annotation, use standardized formats (such as JSON-LD, CSV, or common ontologies like Schema.org), and enable efficient retrieval through APIs or vector databases.75% similar
