IoT products collects the dataset of millions of devices worldwide with redundant data consisting from MAC addresses, boot-priority failures, IP Addresses etc. Today, as usually I will do a dumb start with a large IoT data set with MangoDB which reduces the hassle to utiltize the ORM methodologies to develop large applications for data-query.
Mangodb records the data as a document which is like json data structure key value pairs. values normally to vary include sub-tree collection of array inside a dictionary like data collection.
