Comprehensive Detailed Step-by-Step Explanation with All Enterprise Geodata References:

AnEnterprise geodatabaseis the most appropriate choice for this scenario due to the following reasons:

1. Requirement to Store Data Locally on Organization's Servers

AnEnterprise geodatabaseallows organizations to store GIS data locally in their own database management systems (DBMS), such as PostgreSQL, SQL Server, or Oracle.

This meets the requirement of maintaining control over data storage and ensuring the data resides within the organization's infrastructure.

2. Editing GIS Data via Web Services

Enterprise geodatabases seamlessly integrate with ArcGIS Server, enabling data editing via web services.

Organizations can publish feature services to allow authorized users to edit GIS data in real-time or in a disconnected environment (via sync).

These services support advanced editing workflows, including versioning and conflict resolution.

3. Indexing Specific Business Fields for Performance

Enterprise geodatabases offer robust indexing options to enhance query and editing performance.

You can:

Create attribute indexeson fields that are frequently queried.

Usespatial indexesto improve the speed of spatial queries.

This level of customization helps meet the performance demands of specific business workflows.

4. Advantages Over Other Storage Options

File Geodatabase:

While it is suitable for smaller datasets and local storage, it does not support multi-user editing, integration with web services, or advanced indexing for business fields.

Hosted Relational Database:

This option is part of ArcGIS Online or ArcGIS Enterprise managed services and stores data in the cloud, which contradicts the requirement for local storage.

It also does not provide the same level of control or indexing capabilities as an enterprise geodatabase.

Conclusion:

AnEnterprise geodatabasenot only meets all the stated requirements (local storage, web service editing, and indexed fields for performance) but also provides additional scalability, security, and multi-user editing capabilities.

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.
