A traditional DB (like Oracle) has quite a traditional design inside. Each connection == a separate thread plus of lots of internal data structures dedicated to that specific thread. Those threads do share data page caches, etc usually though locking. They don't usually known anything else about each other. Each one will read DB meta from data page caches, fetch the data, etc
