Application Architecture for Replication Systems

The architectural design of your replication system determines the overall success of your replication environment. As an application designer and user, you need to explore the various options before you implement Replication Server.

• Application Types
  Determining the type of Replication Server application you build determines, in part, the replication strategy you use.
• Effects of Loose Consistency on Applications
  Data in a replicate database is “loosely consistent” with data in the primary database.
• Methods for Updating Primary Data
  In a replication system, the primary copy of a data row is the definitive copy. An update committed in the primary database is authoritative and is distributed to all databases with subscriptions for the data.
