So, what exactly is a vector database? A vector database is a specialized type of database that indexes and storesvector embeddings for fast retrieval and similarity search. Unlike traditional scalar-based databases, vector databases are designed to handle the complexity and scale of vector data, making it easier to extract insights and perform real-time analysis.
Vector databases offer a range of features, including CRUD operations (create, read, update, delete), metadata filtering, and horizontal scaling. These features enable efficient data management and make it easier to handle large volumes of vector data.
One of the key advantages of vector databases over standalone vector indices is their comprehensive data management capabilities. Vector databases not only store vector embeddings but also allow for metadata storage and filtering. This means that in addition to querying based on vector similarity, you can also filter and search for vectors based on associated metadata, making the search process more dynamic and flexible.
Another benefit of vector databases is their scalability. As your data volumes grow and user demands increase, vector databases can scale horizontally to meet those needs. This scalability ensures that your database remains performant and responsive as your data ecosystem expands.

In contrast to traditional databases that store scalar values in rows and columns, vector databases operate on vectors, making them well-suited for handling vector data efficiently.
Vector databases utilize algorithms for approximate nearest neighbor (ANN) search to optimize the search process. These algorithms play a crucial role in finding similar vectors and retrieving relevant information from the database.
The first step in the working of a vector database involves indexing. Indexing algorithms like Product Quantization (PQ), Locality-Sensitive Hashing (LSH), or Hierarchical Navigable Small World (HNSW) are used to map vectors to a data structure that enables faster searching.
Once the vectors are indexed, querying algorithms come into play. These algorithms compare the indexed query vector to the indexed vectors in the dataset to find the nearest neighbors. By performing distance calculations, such as Euclidean distance or cosine similarity, the system identifies the most similar vectors.
However, the process does not end with querying. Post-processing steps may be applied to retrieve the final nearest neighbors and re-rank them using a different similarity measure. This post-processing ensures that the most relevant results are presented to the user, enhancing the accuracy of the similarity search.
Overall, the combination of indexing, querying, and post-processing algorithms allows vector databases to efficiently handle vector data and deliver accurate results in similarity search tasks.
Vector databases employ various algorithms to create efficient vector indexes. One such algorithm is random projection, which projects high-dimensional vectors onto a lower-dimensional space using a random projection matrix. This technique reduces the dimensionality of the vectors while preserving their similarity relationships.
