What characteristics does Reference data have that distinguish it from Master Data?

Show Suggested Answer Hide 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.

Wait, is this a trick question? What if the answer is secretly 'all of the above'? Gotta keep those IT folks on their toes, you know!

A and D both sound reasonable to me. I'm leaning towards D, but I could be wrong. Maybe I should have studied harder for this exam.

Hmm, I'm not sure. E kinda makes sense - reference data is used for transactions, isn't it? This is a tough one.

D seems like the obvious choice here. Reference data is supposed to be less complex and smaller than master data, right?
