You got a valid answer, unlike the ones I gave you, from @daniel_scout at How can MongoDB be used for predictive maintenance models in smart vehicles? - #2 by daniel_scout.
The decent thing to do before going forward with you sea of vague question is to thank Daniel for his. Mark the thread as solved if you are happy with the answer. Or follow with specific answers.
Most likely you will not do the decent thing. You are not that kind of participant.
