ABSTRACT
Many IT departments are beginning to work with sensor data – but sensor data is different from transaction data. Sensor data may arise out of IoT applications or operations engineering integrations with IT. The consequences of application failure with sensor data may result in the loss of millions of dollars, explosions, or death. Sensor data is not accurate, and all values must be cross-checked before critical action is taken. Sensor data is voluminous and is often stored in time-series databases. It is important not to confuse tag databases with metadata tags. Finally, sensor data often lacks all context which must be added.
