Data modeling is the act of describing and evaluating all the kinds of data that an organization creates and gathers, as well as the connections between those data points. It assists in identifying the information requirements for various business processes by giving a visual representation of data sets and their business context. Today, data modeling is more important than ever, as technologists battle an onslaught of unstructured data (text, audio, video, raw sensor output) at volumes and velocities that exceed the capabilities of conventional systems, including iot sensors, location-aware devices, clickstreams, and social media.
