Ramesh #NotGoingBackA big part of this technology is automated reasoning (not AI) with #OWL Direct Entailments & more.
In #relationalDB, you may only retrieve what you've explicitly put into the database.
In #graphDB with OWL reasoning, the system INFERS additional info beyond what you put in, based on strict definitions of Descriptive & First Order Logic.
So, you can glean additional inferences, sometimes subtle, based on what you actually input into the DB.
