telling the Information Management story Confidential © Bloor Research 2009 telling the right story Confidential © Bloor Research 2012 Agenda What is data replication? When would you use it? What are its requirements? Putting it into context

telling the Information Management story Confidential © Bloor Research 2009 telling the right story Confidential © Bloor Research 2012 What is data replication? “The process of copying a portion of a data source from one environment to another and keeping the subsequent copies of the data in sync with the original source. Changes made to the original source are propagated to the copies of the data in other environments.”

telling the Information Management story Confidential © Bloor Research 2009 telling the right story Confidential © Bloor Research 2012 When would you use data replication? Data warehousing and BI Loading real-time data for operational BI Supporting real-time query/reporting Integrating CEP with operational data Operational synchronisation e.g. Lookers v Bookers e.g. synchronising (POS and) central pricing data High/continuous availability Data migration (zero downtime) Master data management To update/broadcast from a hub High/continuous availability …
