Scenario Overview:

The GIS data administrator needs to prepare data for offline workflows.

Offline workflows allow users to take data offline for use in disconnected environments, typically for field operations.

Why Enable Sync?

Sync must be enabled on the feature service to allow offline workflows. This capability ensures that edits made offline can later be synchronized with the enterprise geodatabase.

When sync is enabled, data can be downloaded for offline use in supported applications like ArcGIS Field Maps, and changes can be synchronized back to the geodatabase.

(ArcGIS Documentation: Sync)

Alternative Options:

Option A: Enable Archiving

Archiving tracks historical edits but is not required for offline workflows.

Option B: Add Global IDs

While Global IDs are required for enabling sync, adding them alone does not fully configure the dataset for offline workflows.

Thus, to prepare data for offline workflows, the administrator must enable sync on the dataset.

Scenario Overview:

A one-way replica from parent to child geodatabase is created for a single feature class.

The data owner adds a new attribute field in the parent geodatabase, calculates values, and attempts to synchronize the replica.

The new field and its values do not appear in the child replica, even after manually adding the field to the child geodatabase.

Why Recreate the Replica?

The issue arises because schema changes (e.g., adding new fields) are not automatically propagated in one-way replication workflows. Synchronization only applies to data changes, not schema updates.

To ensure the schema changes are recognized, the replica pair must be recreated with the updated schema. (ArcGIS Documentation: Geodatabase Replication and Schema Changes)

Steps to Resolve the Issue:

Unregister the Replica: Remove the existing replica pair from both the parent and child geodatabases.

Recreate the Replica: Create a new one-way replica between the parent and child geodatabases. This new replica will include the updated schema.

Synchronize Changes: Perform synchronization to transfer data, including the new field and calculated values, to the child geodatabase.

Alternative Options:

Option A: Enabling replica tracking does not address schema synchronization and would not resolve the issue.

Option B: Running Feature Compare is helpful for analyzing schema differences but does not propagate schema changes.

Thus, the data owner must unregister the replica pairs, recreate the replica with the updated schema, and synchronize changes to resolve the issue.

Scenario Overview:

The wells feature class has one row per well.

The well_inspections table has one row for each inspection of a well.

Inspection dates from the well_inspections table need to be displayed as labels clustered around each well on the map.

The goal is to establish a connection between these two datasets without permanently joining them, as the data is being displayed dynamically (inspection dates are clustered around the wells).

Relates in Geodatabases:

A relate is a type of table association in which tables are linked by a common key field but remain separate.

Relates allow for dynamic queries to retrieve related records without duplicating or permanently associating the data.

Using a relate, you can query all inspection dates for a specific well dynamically, display them on the map as labels, and preserve the integrity of both the wells and inspections datasets.

(ArcGIS Documentation: Relates)

Alternative Options:

Option A: Join

A join merges two tables into one virtual table, based on a shared key. However, this approach is static and inappropriate for displaying dynamically clustered labels since the tables would need to be rejoined after every update.

Option C: Relationship Class

A relationship class is a more permanent association that enforces rules between two datasets. It is ideal for maintaining relationships between data but is unnecessary for dynamically labeling inspection dates on the map.

Thus, a relate is the most efficient and appropriate option for this scenario.

To identify which user was responsible for creating each feature in a global enterprise geodatabase, enabling editor tracking is the appropriate strategy.

1. What is Editor Tracking?

Editor tracking records metadata about feature creation and updates, including:

Who created or updated a feature.

When the feature was created or updated.

This information is stored in four additional fields:

Creator

Creation Date

Editor

Edit Date

2. Advantages of Editor Tracking

Automatically tracks and populates user and timestamp fields for feature edits.

Requires no manual intervention by users, ensuring accuracy and consistency.

Works seamlessly in multi-user environments, including enterprise geodatabases.

3. Why Not Other Options?

Add a Global ID:

Global IDs are used to uniquely identify features but do not track user edits or changes.

Use Relationship Classes:

Relationship classes establish connections between features or tables. They are not designed to record user actions or metadata.

Steps to Enable Editor Tracking:

Open ArcGIS Pro and connect to the enterprise geodatabase.

Right-click the feature class or dataset and select Manage > Enable Editor Tracking.

Specify the fields for storing creator, editor, creation date, and edit date.

Save and apply the changes.

Conclusion:

Enabling editor tracking is the most effective strategy to identify which user created each feature in a global enterprise geodatabase.

To ensure that the parent geodatabase can be fully compressed, even with unacknowledged data change messages, the replication must be configured to replicate only the base tables.

1. What Happens with Unacknowledged Messages?

In traditional one-way replication, unacknowledged data change messages in the delta tables (Adds and Deletes) prevent full compression of the parent geodatabase.

By replicating only the base tables, the replication avoids using delta tables entirely, allowing the geodatabase to be fully compressed.

2. Why Replicate Only the Base Tables?

No Dependency on Delta Tables: This configuration ensures that the replication is based directly on the base table contents. As changes are not recorded in delta tables for replication, the parent geodatabase can be fully compressed without any impact.

Read-Only Copies: The replicated data in the child geodatabase will be read-only, which aligns with the requirement for regional offices.

3. Why Not Other Options?

Use the Full Replica Access Type:

Full replica access allows editing in the child geodatabase, which is unnecessary for read-only requirements. It also uses delta tables, preventing full compression.

Use the Archiving Option:

Archiving tracks historical edits and is unrelated to the replication or compression process. It does not solve the problem of unacknowledged messages blocking compression.

Steps to Set Up One-Way Replication with Base Tables:

Open ArcGIS Pro and connect to the parent geodatabase.

Use the Create Replica tool and select One-Way Replication.

Choose the option to replicate base tables only during the configuration process.

Define the datasets to replicate and complete the replication setup.

Conclusion:

Configuring replication to replicate only the base tables ensures that the parent geodatabase can be fully compressed, even with unacknowledged data change messages.
