How should derived or materialized reporting views be designed and maintained in Clarity?

• A. Create materialized views or derived tables for complex analytics; ensure they are refreshed on a schedule and validated against source data.
• B. Store all analytics in the OLTP transactional table.
• C. Use indexing-only optimization without refresh.
• D. Avoid any precomputed views to keep real-time freshness.

Answer: (A)

Precomputing expensive analytics and keeping those results up to date is the way to make reporting fast and reliable. By creating materialized views or derived tables, you store the outcome of long-running calculations and joins so that read queries hit precomputed data rather than recalculating everything each time. Refreshing these views on a schedule lets you balance performance with data freshness, and validating them against the source data catches drift or errors, ensuring the results stay trustworthy. Storing all analytics inside the OLTP transactional table blurs the line between transactional processing and reporting, which can bloat the transactional model, degrade write performance, and complicate analytics. Relying on indexing alone without any refresh won’t provide precomputed results for complex analyses and can still yield stale data. Avoiding precomputed views in favor of real-time freshness alone can overload the system with heavy computations during queries, hurting performance. The materialized/derived approach hits a practical middle ground: fast analytics with controlled, auditable freshness.
