Which of the following describes the relationship between Gold tables and Silver tables?
Which of the following describes the relationship between Gold tables and Silver tables?
Gold tables are more likely to contain aggregations than Silver tables. In the context of a typical 'Bronze-Silver-Gold' data lake architecture, Silver tables represent an intermediary, more refined stage of data that has undergone cleaning, schema enforcement, and some initial transformations. Gold tables, on the other hand, typically represent the final, highly processed stage where data has been enriched, aggregated, and transformed to provide valuable insights for analytical purposes. Aggregations are more prevalent in Gold tables because they are prepared for final consumption by business users and analytical applications.
A. Gold tables are more likely to contain aggregations than Silver tables. In some data processing pipelines, especially those following a typical "Bronze-Silver-Gold" data lakehouse architecture, Silver tables are often considered a more refined version of the raw or Bronze data. Silver tables may include data cleansing, schema enforcement, and some initial transformations. Gold tables, on the other hand, typically represent a stage where data is further enriched, aggregated, and processed to provide valuable insights for analytical purposes. This could indeed involve more aggregations compared to Silver tables.
Option A
THE ANSWER C IS INCORRECT! Silver tables usually contain data that is commonly a little more refined than Bronze tables. Meaning they contain data that is likely cleaned and contains no duplicates. Gold tables usually contain aggregate or "corrected" data.
Correct answer is B. I saw this from the Databricks practice test. It's a little blurry, but this is the correct answer.
To me it seems A and E is equally correct. Truthfull is not very defined in the question. But Gold layer typically have more rules and transformations in order to be consumed by business and reports. So It could be intepreted as more "truthfull". Or am I wrong here?
A os correct
Correct answer is B!
In some data processing pipelines, particularly those following a "Bronze-Silver-Gold" data lakehouse architecture, Silver tables are indeed considered a more refined version of raw or Bronze data. Gold tables, which represent the final stage of data processing, typically contain highly refined, aggregated, and ready-to-consume data. Therefore, it's common for Gold tables to contain aggregations, as they often represent the final, summarized, and aggregated view of the data. On the other hand, Silver tables may contain partially aggregated or cleansed data but are not typically the final destination for aggregated data. "Gold tables are more likely to contain aggregations than Silver tables" is accurate, making option A a valid choice.
A; row data = bronze data > silver data > golden data C is so opposite and wrong
Raw Data > Bronze Data > Silver Data > Golden Data
correct is A
Correct is A
Correct: A
B 2 Type of Tables in Delta Lake data lake architecture Gold tables are the most refined and valuable tables in the data lake, while Silver tables are less refined and less valuable. Gold tables are typically used for downstream analysis and reporting, while Silver tables are typically used for data exploration and experimentation. Gold tables typically contain the most refined, high-quality, and valuable data in an organization's data architecture. They often represent the final output or result of data processing pipelines, where data has undergone extensive cleansing, transformation, and aggregation. Gold tables are typically used for critical business analysis, reporting, and decision-making processes. Option A: Gold tables are not necessarily more likely to contain aggregations than Silver tables. Option C: Gold tables are more likely to contain a more refined view of data than Silver tables. Option D: Gold tables are not necessarily more likely to contain more data than Silver tables.
The data itself should be the same. However the Transformations are not. Gold Layer, as I understand it, is more probable to have more transformations as its ready for reports and business consumptions. So A? "The Gold layer is for reporting and uses more de-normalized and read-optimized data models with fewer joins. The final layer of data transformations and data quality rules are applied here." https://www.databricks.com/glossary/medallion-architecture
The correct answer is B. Gold tables are typically considered to be the most valuable and trusted data assets in an organization. They represent the final, refined view of the data after all cleaning, transformations, and enrichments have been performed. Silver tables are the intermediate tables that feed into the Gold tables, and are typically used to perform data cleansing, filtering, and enrichment before the data is promoted to Gold.
