🎓 Vector databases store meaning, not just data.
Regular databases match exact words. Vector databases turn text, images, or code into number patterns and find what's similar in meaning, even if the wording is totally different.
Builders use them to give AI models memory and context beyond their training data.
Example: an AI trading assistant searches years of news and finds every article "similar" to a Fed rate cut, not just ones containing that exact phrase.
Takeaway: vector databases let AI search by meaning, not keywords.
