Implementation Strategies

There are various models and strategies for implementing your replication system. Replication Server includes procedures and sample scripts that you can adapt to your own application.

• Overview of Models and Strategies
  There are various data replication models for replicating data.
• Basic Primary Copy Model
  The basic primary copy model allows you to replicate data from a primary database to destination databases.
• Distributed Primary Fragments Model
  In a distributed primary fragments model, tables at each site contain both primary and replicated data.
• Corporate Rollup
  In the corporate rollup model, multiple primary fragments maintained at remote sites are consolidated into a single aggregate replicate table at a central site.
• Redistributed Corporate Rollup
  The redistributed corporate rollup model is the same as the corporate rollup model, except the consolidated table is redistributed back to the remote sites.
• Warm Standby Applications
  In a warm standby application, Replication Server maintains a pair of databases from the same vendor, one of which acts as the backup of the other.
• Model Variations and Strategies
  Model variations and other strategies are useful when implementing your replication system design.
