Abstract
A sequence online analytical processing (S-OLAP) system 50 for analysing an event database (41) storing events (12), the system (50) comprising: an S-OLAP engine (53) to compute an S-cuboid (49) for a query on the event database (41); a sequence query engine (54) to form part of the S-cuboid (49) by performing the steps of: selection, clustering, sequence formation and sequence grouping; a cuboid repository (52) to store computed S-cuboids (49) and to be searched by the S-OLAP engine (53) for an S-cuboid query to determine whether an S-cuboid has previously been computed; and a sequence cache (56) to cache constructed sequence groups.
