To move an enterprise geodatabase to a new server while keeping it intact, theRDBMS export/importprocess is the appropriate method.

1. Why Use RDBMS Export/Import?

Enterprise geodatabases are tightly integrated with the underlying RDBMS (e.g., SQL Server, PostgreSQL, Oracle). Exporting and importing the entire database ensures that:

All geodatabase configurations (e.g., tables, indexes, metadata) are preserved.

No data integrity is lost during the migration process.

This method maintains the geodatabase’s structure and relationships.

2. Why Not Other Options?

Export to File Geodatabase:

While exporting to a file geodatabase allows for data transfer, it does not preserve the enterprise geodatabase structure, including user permissions, versioning, and replication configurations.

Two-Way Replication:

Replication is designed for synchronizing data changes between geodatabases, not for moving an entire geodatabase to a new server. It may also leave some administrative configurations behind.

3. Steps for RDBMS Export/Import

Export the Database:

Use the RDBMS tools (e.g., pg_dump for PostgreSQL, SQL Server Management Studio) to create a full backup of the geodatabase.

Ensure all related schemas, indexes, and metadata are included.

Import to the New Server:

Set up the RDBMS on the new server and configure it for enterprise geodatabases.

Import the backup file to restore the geodatabase on the new server.

Post-Migration Steps:

Reconfigure connections in ArcGIS Pro or ArcGIS Server to point to the new geodatabase.

Test to ensure all functionality works as expected.

Conclusion:

TheRDBMS export/importprocess ensures a complete migration of the enterprise geodatabase to a new server while preserving all configurations and data integrity.

Scenario Overview:

Multiple editors need tocollaboratively editthe same dataset using a web application.

Requirements:

Editors work inisolationuntil they reach a stopping point.

Edits are shared with others at the stopping point.

Editors can view shared edits without sharing their own.

Branch Versioning in Enterprise Geodatabases:

Branch versioning is specifically designed for collaborative editing inweb-based workflows.

It supportsisolated editingby creating branches for each editor and allows users to reconcile and post changes at their discretion.

Editors canchoose to reconcile shared changes without posting their own edits, fulfilling the requirement to view shared edits without sharing their own.(ArcGIS Documentation: Branch Versioning)

Key Features of Branch Versioning:

Supports Web Applications:Designed to work seamlessly with feature services, enabling real-time collaborative editing.

Isolation:Each editor can edit independently in their branch.

Reconciliation:Editors can reconcile and view changes made by others without posting their edits.

Flexible Sharing:Editors control when to post edits.

Alternative Options:

Option B: Traditional versioned with editor tracking enabled:

Traditional versioning supports isolated editing, but it does not provide the flexibility to view shared changes without posting your own edits.

It is also not as well-suited for web-based collaborative workflows.

Option C: Traditional versioned with the option to move edits to base:

Moving edits to base bypasses versioning workflows entirely and is not designed for collaborative editing.

Thus,branch versioningis the optimal solution for the requirements of this collaborative editing workflow in a web application.

 Understanding the Scenario:

The request involves creating a view that dynamically combines data from aversioned feature classand anonspatial table.

The data needs to be from achild versionand updated dynamically.

 Key Considerations:

Versioned Feature Class:Standard feature classes in versioned geodatabases store edits in delta tables (adds and deletes). Accessing data from a specific version requires using theversioned view, which includes these edits.

Dynamic Updates:Views created on the versioned view ensure that the data reflects the most current version edits.

 Steps to Create the View:

Identify the versioned view for the feature class (created automatically during versioning).

Create a SQL query to join the versioned view and the nonspatial table on the appropriate key(s).

Save the SQL query as a database view.

 References:

Esri Documentation: Versioned Views.

Creating Views with Versioned Data: Guidelines for joining versioned views with other tables in SQL.

 Why the Correct Answer is C:Using the versioned view ensures that data reflects edits from the specified child version. Joining this view with the nonspatial table meets the requirement for dynamic updates. Options A and B would not provide data from the versioned child version dynamically.
