A distributed analytics method and system for processing hit data and producing reports. The hit data includes attributes and values representing activities of a visitor on a web site. The distributed analytics system may include log processors to read and parse the hit data. Analytics generators are configured to read and process the parsed hit data and store the processed data in one or more analytics data stores, which are associated with bands. Analytics processors read and merge data from the analytics data stores associated with the bands, and produce intermediate report deltas. Report generators are configured to receive the intermediate report deltas and produce and store one or more report segments in report data stores. External data can be combined with the data being processed. Report processors are configured to read data from the report data stores and produce a final result based on the report segments.
