The main difference is that you can have code waiting for a query to yield results. Imagine a chat service which has a separate process for each user’s TCP connection. Normally, when a new message arrives, you have to tell each user’s connection process to send the message over the network. In a tuple space system, each connection process can wait for new messages to be added to the database and send them automatically.
