SNOW-CAD Creating and customizing tables and data Practice Question
A senior developer advises an associate to create a new table for storing incident-related attachments metadata. The table should not have its own workflow or assignments but should be related to incidents. Which table creation approach is best?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a table with a reference field to the Incident table.
The best approach is to create a custom table with a reference field to the Incident table (Option D). This allows storing metadata related to incidents without inheriting Incident's workflow, assignments, or other behaviors. Option A is incorrect because a database view is read-only and cannot store new data. Option B is incorrect because extending the Attachment table would inherit attachment-specific behaviors and is not appropriate for custom metadata. Option C is incorrect because extending the Incident table would inherit all Incident's features, including workflow and assignments, which the requirement specifically avoids.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a database view that joins Incident and Attachment tables.
Why it's wrong here
Database views are read-only and cannot store custom data.
- ✗
Create a table that extends the Attachment table class.
Why it's wrong here
The Attachment table is a system table not intended for extension.
- ✗
Create a table that extends the Incident table.
Why it's wrong here
Extending Incident would inherit all its workflows and assignments, which is not desired.
- ✓
Create a table with a reference field to the Incident table.
Why this is correct
A reference field allows linking to Incident without inheriting its behavior, suitable for metadata storage.
