Databricks Certified Data Engineer - Associate

Explanation

Let's analyze each option:

A. Table - ✅ CORRECT

• Tables are persistent data entities that are saved to physical storage (like Delta Lake)
• They can be accessed by other data engineers in different sessions
• They exist beyond the current session and can be queried by multiple users
• Tables store data physically on storage

B. Function - ❌ INCORRECT

• Functions are reusable code blocks, not data entities
• They don't store data from tables
• They are not saved to physical locations as data storage

C. View - ❌ INCORRECT

• Views are virtual tables that don't store data physically
• They are saved definitions that reference underlying tables
• While they can be used by other engineers in other sessions, they don't save data to a physical location
• Views only store the query definition, not the actual data

D. Temporary view - ❌ INCORRECT

• Temporary views are session-scoped and cannot be accessed by other data engineers in other sessions
• They are not saved to physical locations
• They disappear when the session ends

Key Requirements from the question:

1. Created from a couple of tables ✓ (Tables can be created from other tables using CTAS or similar operations)
2. Used by other data engineers in other sessions ✓ (Tables are accessible across sessions)
3. Saved to a physical location ✓ (Tables store data physically in storage)

Only Table meets all three requirements. Views (including temporary views) don't save data physically, and functions aren't data entities created from tables.
