It therefore goes without saying that data modeling standards are an essential requirements for companies that conduct projects, where data has to be analysed and defined in a particular manner. It discusses the results of four different data modeling surveys in 2007, 2009, 2011, and 2012 taken by some of the leading industry … Where unanticipated data was added to existing forms, or where form fields designated for one kind of data was used to another kind, confusion occurred, and mis-communication resulted. While governments across the world are strategizing to solve challenges like procurement, distribution and storage of vaccines, they are also looking at addressing resistance from anti-vaxxers and questions on the effectiveness and side effects of the vaccination. Used to model data in a systematic and proper manner, data modelling techniques helps companies to manage data as a valuable resource. Data Modeling Challenges Attendees are presented with several data modeling situations. New data points are continuously added, tested to see if they improve forecasts and then tuned for each geography. The challenges for machine learning models are finding useful COVID-19-related data sets and transforming them into a consumable format.
