What is Vector Database?
A database designed to store and quickly search through embeddings, which represent data as lists of numbers.
Why It Matters
Vector databases power semantic search and AI applications that need to find similar content quickly.
Real-World Example
Storing product descriptions as vectors so customers can search by meaning rather than exact keywords.
“Understanding terms like Vector Database matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
