Abstract: A backend data aggregation and customer experience (CX) systems and methods for processing very-large enterprise CX data. A columnar data store has a transform processor coupled thereto via a data communication network. The transform processor is configured to receive customer experience data from a plurality of data sources and to dynamically transform the received data into a columnar data schema format for storage in the columnar data store. A dynamic Object-Relational Mapper (ORM) is configured to dynamically map the transformed data to structured data based on metadata associated therewith and to store the structured data in the columnar data store.
