Show Suggested Answer

Suggested Answer: C

Reference data and master data are distinct in several key characteristics. Here's a detailed explanation:

Reference Data Characteristics:

Stability: Reference data is generally less volatile and changes less frequently compared to master data.

Complexity: It is less complex, often consisting of simple lists or codes (e.g., country codes, currency codes).

Size: Reference data sets are typically smaller in size than master data sets.

Master Data Characteristics:

Volatility: Master data can be more volatile, with frequent updates (e.g., customer addresses, product details).

Complexity: More complex structures and relationships, involving multiple attributes and entities.

Size: Larger in size due to the detailed information and numerous entities it encompasses.

A) It is more volatile and needs to be highly structured. Hmm, I thought Reference data was supposed to be less volatile than Master data.

C) It always has foreign database keys to link it to other data. I'm not sure that's always true for Reference data, seems a bit too specific.

That's a good point, Dallas. It does make sense that Reference data comes from an external source. Maybe I should reconsider my answer.

I disagree, I believe Reference data is always data from an outside source, like a governing body. Option B seems more fitting to me.
