Abstract: A computer-implemented method is disclosed for processing metrics via a controller. The controller comprises a processor and a memory storing program instructions which when executed by the processor causes implementation of the steps of generating or receiving metrics characterising digital traffic and/or related user behaviour from one or more sources and generating or receiving a tabular dataset associated with the metrics, wherein the dataset comprises rows of metrics and dimensions in which each row represents a subset of a metric grouping characterised by a combination of dimensions. The processor further implements the steps of receiving one or more partition identifiers representing a data structure of dataset partitions, assigning one or more metric groupings to one or more partition identifiers and analysing the dataset according to partition identifiers.
