REVIEWER: Mark Spear, Lennon program director at Atos Origin.

BACKGROUND: Atos Origin is an international information technology services company with annual revenues of more than EUR 5 billion and 45,000 employees in 50 countries. Atos Origin manages Lennon, the hosted rail-ticketing analytics service for the Rail Settlement Plan (RSP), which is part of the United Kingdom's Association of Train Operating Companies (ATOC). The Lennon project requires that 401 days of data on transactional sales from all of the UK's train operating companies be kept accessible to users, at varying levels of aggregation. The data must be archived after 401 days, but it must still be available for quick restoration at any time for analytic purposes. Atos Origin was contracted to maintain this service for 15 years, and we estimated that more than 24 terabytes of storage would be required to hold the data for this period if a traditional relational warehouse design were adopted.
