Does your business collect too much data?

Another thing to look at is are you collecting useful data? When you design your collection, are you collecting too many points? I'm a scientist who once was collecting data for combustion toxicology, things like gas sensor readings and temperatures. The first runs were done at 10 readings per second. After a few runs, we started analyzing the data. It turns out that we were able to reduce the frequency of points to once every 5 seconds without losing any information. Things weren't changing fast enough to need 10 data points per second.

Make sure the data you are collecting is appropriate to your need.

Sadly many business line management have a clueless LETS COLLECT IT ALL, mentality.

They store terabytes of data and do nothing with it becaause it over whelms them.

Then it all becomes a huge liability when states like Massachusetts enact strict privacy laws.
