The device keeps its readings in one format and the gateway wants rows in a SQL database, so somebody writes a converter. Then somebody has to keep that converter alive for as long as the device stays in the field, which can easily be ten years.</p> <p><a href="https://altsql.com/">AltSql</a> takes the converter out. Its base engine, AltSql Core, compiles to about 15 KB of code for a microcontroller. The device keeps its readings and settings in its own flash and goes on deciding from its own data when the connection goes. Its gateway stores the very same records, byte for byte, and answers SQL over them.</p>
