A GIS analyst creates a database view. When the database view is loaded into the map, performance is suboptimal. Which workflow should the analyst…

Registering a database view with an enterprise geodatabase is the correct workflow to improve performance. This process adds the view to the geodatabase's system tables and, most importantly, defines a unique identifier (ObjectID) field. ArcGIS clients rely on a unique ObjectID for fast feature retrieval, selection, and rendering. Without a registered ObjectID, ArcGIS must scan the view on the fly to identify rows, leading to the suboptimal performance described. Registration allows ArcGIS to leverage database indexes and perform optimized spatial and attribute queries, directly addressing the performance bottleneck.

A. Export to shapefile: This creates a static, disconnected copy of the data. It does not improve the performance of the live database view and severs the dynamic link to the source database.

B. Join to another feature class: This is a data analysis operation. Joining the view to another dataset would add computational overhead and likely decrease, rather than improve, performance.

Esri ArcGIS Pro Documentation, "Register a table or view with the geodatabase": "When you work with a spatial table in the database that was not created with ArcGIS, you must register it with the geodatabase to take advantage of geodatabase functionality... When you register a table, an ObjectID field is added to the table if one does not exist... The ObjectID is used by ArcGIS to uniquely identify rows in the table." This unique identification is fundamental for performance.

2. Esri ArcGIS Pro Documentation, "Query layers": "For a query layer to perform well, the query that defines it should be optimized for the database... You must define a query that has a field or fields that have unique values... ArcGIS Pro uses these unique-valued fields to perform operations that depend on specific rows in the dataset." This highlights the critical role of a unique identifier for performance, which the registration process formally establishes for a view.

Penn State University, GEOG 485: GIS Database Development and Administration, Lesson 7: Loading and Registering Data: "When you have spatial data in a DBMS that was not created through ArcGIS, you can register it with ArcSDE. Registering the data makes it possible to view, query, and edit the data in ArcGIS... The main benefit of registering data is that it enables you to define how certain properties of the table should be treated by ArcGIS. For example, you can specify which column should serve as the unique ID field (ObjectID)."
