Which type of rule may require Durable Data?

• A. Complex expressions
• B. Member formulas
• C. Dynamic calculations
• D. Custom calculations

Answer: (D)

Durable Data is a persistence mechanism used by calculation logic to store and reuse values across recalculations or rule executions. Custom calculations are the type of rule where you write explicit logic that can read from and write to this durable store. Because you can cache results, share intermediate values, or carry state between calculations, custom calculations may rely on Durable Data to improve performance or enable cross-step data sharing. Other rule types are generally evaluated in-memory or reference existing member data without writing to a persistent store, so they don’t rely on Durable Data in the same way. Complex expressions and member formulas compute values directly from inputs, and dynamic calculations re-evaluate as data changes, rather than storing results for later reuse.
