Vector Database

Definition ∞ A vector database is a specialized database designed to store and efficiently search data represented as high-dimensional vectors. This type of database stores information as numerical vectors, which are mathematical representations of data points often generated by machine learning models. It enables rapid similarity searches and retrieval of semantically related data, rather than exact matches. Vector databases are particularly useful for applications requiring context-aware search, recommendation systems, or handling unstructured data, including large language model outputs.
Context ∞ Vector databases are gaining prominence in the digital asset and Web3 space for managing and querying complex, high-dimensional data, such as NFT metadata, on-chain analytics, or decentralized identity information. Their ability to perform semantic searches is critical for developing more intelligent and responsive decentralized applications and AI-powered crypto tools. News often highlights the integration of vector databases into new protocols or analytical platforms, showcasing their role in advancing data accessibility and utility within the ecosystem.
