The challenges that I feel would be that due to a large volume of data, there could be a problem with data quality, there would be problem with how it is collected because different people are collecting the data, there would be a problem with that. So I guess the first thing that would be needed to be done in such a case where the volume is such a large number would be to validate the data and there are different ways to do that. After validating the data, if it's necessary, then cleaning the data would be really important because you can't really analyze the data before making it a cleaner version of the original data. Sometimes when you get a clean data, you could easily visualize it properly and the final step would be just to identify any trends and then how would you present it. The visualization of the data is the most important, I feel, because there's also non-technical background people who will be seeing the dashboard. So in case of that, a simple dashboard which would highlight the problem and what the solution is and why it's happening would be very beneficial.
