BigData sketch and possible usecases The document discusses using big data to enable data-driven business decisions and actions. It proposes collecting and storing various data types in a data lake. Advanced analytics like machine learning and predictive modeling would then generate interactive visualizations to provide actionable insights. The goal is not to replace existing systems but evolve capabilities around storage, visualization, and decision making to help business teams. Key challenges involve data volume, variety, skills, and governance which require the right technology platforms and cross-functional collaboration.
