Event Data

Event Data:  A Challenge and Opportunity

Virtually every form of information technology produces event data. Sometimes referred to as log data, audit trails or the system of record, event data is a set of chronologically sequenced data records that capture information about what happens in the digital infrastructure.

Event Data is Different from Transactional Data in Traditional Data Warehouses

  • Cumulative volume.  Event data accumulates rapidly and often must be stored for years; many organizations are managing hundreds of terabytes and some are managing petabytes.
  • Format. Because of the huge variety of sources, event data is unstructured and semistructured.
  • Collection. Event data is difficult to collect because of broadly dispersed systems and networks.
  • Time-stamped. Event data is always inserted once with a time-stamp. It never changes.
