This week on Azure Cosmos DB TV Live, Mark Brown welcomes Microsoft Principal Cloud Advocate Paul DeCarlo to the show to recap a July 2022 hackathon at the Microsoft Offices in New York City. Microsoft and Oxford University partnered for A Tale of Two Cities: Data & AI Hackathon in New York City that ran from July 21 - 23. Participants were challenged to use a provided dataset between New York City and London to develop analytical insights and solutions to uncover behavioral patterns before, during, and after the pandemic. The event focused on a very specific problem statement, “How have major cities like London and New York been affected by Covid-19 and how can we use historical data to explore how these effects might impact us in a Post-Covid world”. In this session, we’ll talk about how teams were able to leverage Azure Cosmos DB, by loading data using Azure Data Factory to then process with Azure Synapse and visualize correlations using PowerBI.
