That was an excellent video with explanations!! will the queries hit suppose to be in warehouse or oltp? I believe warehouse will have only the histories.Data could be ingested to warehouse from sources(may be oltp) monthly or yearly basis.In that case, if the business needs to view the details, where usually it suppose to retrieved from?
