TechnicalAI glossary
Vector database
A database designed to store embeddings, those lists of numbers that capture the meaning of a text or image. It instantly retrieves the content whose meaning is closest to a query: it's the search engine that powers RAG.
In other words
A library organised by affinity of ideas rather than alphabetical order: books on the same subject end up on the same shelf.

- What is an "embedding"? The technique that lets a machine understand that "doctor" and "physician" mean the same thing.
An embedding transforms text into a list of numbers that encodes its meaning. We explain this key concept, how it enables semantic similarity search, and why it is the invisible engine behind most enterprise document assistants.
