29
Q

What are the factors that need to be considered before analyzing data?

A

A significant factor that should be taken accounted for is data storage. While it may be of great help to gather and store all the data that we can, we must reduce the processing of complex data and only store small amounts of irrelevant data in the future.

30
Q

How big data is processed in an IOT solution?

A

The data processing elements of an IoT architecture in IoT systems vary depending on the specifics of incoming data, anticipated results, and more. To process big data in IoT solutions, we’ve developed our own methodology.
