Re: 6 Internet Of Things Building Blocks
@Gigi3, in most cases no. For example let's say you have an application where pressure is being measured and let's say 30-35PSI is "normal" and fluctuation is expected so you have a chart of entries every 30 seconds and it looks like 30,32,30,30,34,33,30,31,32,30,30,32, and it goes on like that for months, do you really need each and every 30 second interval? Or is what you need a single entry that reads "normal" for several months and an entry that reads "high" if the pressure creeps up past your "normal" threshold? Keeping each entry is going to take up space, slow down queries over time and just turn into a blur of numbers. This kind of data presentation tends to put the average person to sleep and your data folks just end up averaging those numbers out anyway because they know that no one wants to see one digit intervals on a chart when those intervals don't have any real meaning. Spread that out of over a few years and hundreds of sensors and you can see how this data set could get out of control and still have very little useful data in it.
