Distributing Data Using Geodatabase Replication


Geodatabase replication is a powerful way to extend access to GIS data stored in a multiuser ArcSDE geodatabase across organizations and into the field. This course teaches how to plan for and implement geodatabase replication to support multiuser editing workflows and data sharing initiatives. You will learn best practices for protecting the integrity of your production database while meeting the needs of desktop, mobile, and online users.

Who Should Attend
Database administrators, GIS data managers, and others who need to incorporate geodatabase replication into their organization’s business and versioned editing workflows.

After completion of this course you will be able to:
• Determine the number and type of replicas needed to support your organization’s GISworkflows and applications.
• Plan an efficient synchronization strategy for replicated data.
• Manage schema changes between replicas.
• Perform routine replica management tasks to maintain database performance.
• Create a replica and synchronize edits using a geodata service in a web application

Completion of ArcGIS 2: Essential Workflows and Implementing Versioned Workflows in a Multiuser Geodatabase or equivalent experience is required.
