What is software doing while it queries the database

Design Goals
 No function should directly peform I/O.
 To receive info from disk, network or another
process there must be a callback.
 Stream every thing, never force buffering of data.
 Have built in support for the most important
protocols (TCP, DNS, HTTP).
 Chunked requests and responses
 Keep – alive
 Should be familiar to client­side JS programmers
and old school UNIX hackers.
