Deploying analytics

Although analytics should be agnostic with regard to how the data is fed to the platform, we have to consider several potential pitfalls that can affect the efficiency of the analytics. There are several strategies that we can use to feed I-IoT data to the platform:

• Bulk ingestion, for example, one file daily
• ­Small portion, for example, one file every five minutes
• Data streams, where files are fed continuously with a small latency

• ­ It might be in the wrong order. For example, a data point at 18:00 might be sent at 18:10 and a data point at 17:59 might be sent at 18:11.

• It might have anomalous spikes in it.
• ­It might ...
