Vector Database Glossary Definition

A vector database is a database designed to store, index, and search vector embeddings efficiently.

Vector Database is a Database concept associated with document-oriented storage, where information is organized in flexible document structures rather than only fixed relational tables. In MongoDB contexts, the term may also reflect platform-specific behavior or documentation conventions.

Vector databases support semantic search, recommendation, similarity matching, and retrieval-augmented generation applications.

Developers and data architects use this concept when modeling flexible records, designing application data access, or scaling document-oriented systems.

Related concepts include Document, Collection and NoSQL.
