Geodatabase Replication

• Allows you to distribute copies of data across 2 or more geodatabases

• Databases can be edited independently and then synchronize them as

needed

• Implement as part of business workflow, example:

– Mobile field crews disconnected from network

– Distribute work to contractors

– Maintain copies of data at different

organizational levels

State

County

City

Parent

Replicas can be organized into a tree

Central parent replica can be used

as a hub to propagate changes between multiple child replicas
