GIS Geodatabase Design and Management 4

Question 1

Which geodatabase storage format is best suited for a team of five field collectors working simultaneously without a network connection?

Accepted Answer

File geodatabase replicated to each device

Answer

File geodatabase replicas allow each field collector to work offline independently, then synchronize edits back to the central geodatabase when connectivity is restored.

Question 2

What is a 'mosaic dataset' in a geodatabase used for?

Accepted Answer

Managing and serving large collections of raster imagery as a single virtual layer

Answer

A mosaic dataset is a geodatabase object that catalogs, manages, and serves collections of raster datasets as a unified, queryable raster layer.

Question 3

Which tool is used to upgrade a file geodatabase created in an older ArcGIS release to the current release schema?

Accepted Answer

Upgrade Geodatabase

Answer

The Upgrade Geodatabase tool updates the system tables and schema of a geodatabase to the current ArcGIS release version.

Question 4

In a geodatabase topology, what is a 'dirty area'?

Accepted Answer

A spatial extent where edits have been made but topology has not yet been validated

Answer

Dirty areas are regions marked by the geodatabase where features have been edited since the last topology validation, indicating those areas need to be re-evaluated for rule violations.

Question 5

What is the primary advantage of using 'attribute rules' (introduced in ArcGIS Pro) over traditional geodatabase domains?

Accepted Answer

Attribute rules can enforce cross-field and cross-table validation using Arcade expressions

Answer

Attribute rules use Arcade scripting to implement complex validation, calculation, and constraint logic that can reference multiple fields or related tables, far beyond the simple list/range checking of domains.
