System, methods, and devices for data storage and processing with identity management

Embodiments relate to data storage systems and data processing systems using a data hub, connector grid, and channel services. The systems can extract raw data from a plurality of source systems, and load and store the raw data at a data hub implemented by a non-transient data store. The systems can receive request to generate data for consumption and, in response, transmit generates data sets to channel services. The system can implement event detection and logging. The system can implement policy enforcement and identity management with access controls.
