The usual way is to pull every machine&rsquo;s readings to a server first and ask there. That moves every raw reading, and on a slow or costly link the moving is the expensive part.</p> <p>AltSql Ask turns that around. The gateway takes an ordinary SQL question and compiles it into a small program. It sends that program to every device. Each device runs it against its own records and sends back its share of the answer, and the gateway merges the shares into the rows the same SQL would have given over all the raw data.</p>
