Explanation:
In the Databricks Lakehouse architecture, Bronze tables represent the first layer of data processing. They contain raw data that has been ingested from source systems, but with a schema applied to provide structure and basic organization. This is different from:
- Option A: Bronze tables typically contain the same data as raw files, just structured
- Option B: Truthfulness isn't the primary distinction - both contain the same raw data
- Option C: Bronze tables don't contain aggregates; they contain raw data
- Option D: Bronze tables are actually more refined than raw data because they have schema applied
The key characteristic of Bronze tables is that they preserve the raw data in its original form while adding schema enforcement, making the data queryable and organized while maintaining its original fidelity.
