Often, multiple applications within an enterprise use equivalent data. For example, a
Customer Relationship Management (CRM) system and a Billing system both contain

be updated in both systems. Data synchronization keeps equivalent data across multiple
systems consistent; that is, if data is changed in one application, a similar change is made
to the equivalent data in all other applications.
