VerifiedVector retrieval relies on vector databases for fuzzy matching and cannot precisely express structural relationships, whereas graph retrieval uses graph databases as the storage medium and is specifically optimized for multi-hop traversal queries.62% similarVerifiedVector databases convert text into high-dimensional vectors typically of 768 to 3072 dimensions and use ANN algorithms for retrieval, with mainstream ANN algorithms including HNSW and IVF-PQ.61% similarUnverifiedWhen querying data, AI data agents interact with the semantic layer rather than directly manipulating underlying SQL tables, thereby mapping natural language questions to validated, standardized metric definitions.60% similarUnverifiedAt retrieval time, the user's question is likewise encoded into a vector, and the system uses measures such as cosine similarity to find the top-K chunks closest to the question vector.60% similar
