   3 flagged findings, all verified unverified: an unverified quote attributed to Rohan Kumar (real former Microsoft VP) citing a specific Ignite 2022 session with no verifiable source; an unverified quote attributed to Rimma Nehme citing a specific VLDB 2023 academic conference talk with no verifiable source (and containing an implausible inserted marketing reference to 'the data fundamentals certification' inconsistent with an academic database conference talk); an unverified 'Databricks State of Data + AI report... 87%' statistic with no locatable matching source.

   Before

   "The fundamental error in data architecture is assuming all your data needs to go into a relational database..." -- Rohan Kumar, Corporate Vice President of Azure Data, from Microsoft Ignite 2022 / "The question is never whether to use SQL or NoSQL... The data fundamentals certification teaches candidates to match workload requirements to technology strengths..." -- Rimma Nehme, Principal Research Manager at Microsoft Research, from the VLDB 2023 conference / According to the 2023 Databricks State of Data + AI report, 87% of data teams using cloud platforms work in multi-service environments.

   After

   The fundamental error in data architecture is assuming all data needs to go into a relational database. Matching data format to storage technology is the first, most consequential decision in any data project, and the DP-900 exists precisely because this decision is made wrong so often. (attribution removed) / The question is never whether to use SQL or NoSQL, it is what access pattern the application requires. NoSQL is not better or worse than relational, it is optimized differently. (attribution removed, marketing insertion referencing 'the data fundamentals certification' removed as implausible for an academic database conference talk) / Most data teams using cloud platforms today work across multiple services rather than a single database technology.

   Why: 3 verified fabrications: an unverified quote attributed to real former Microsoft VP Rohan Kumar citing a specific Ignite 2022 session with no verifiable source; an unverified quote attributed to Rimma Nehme citing a specific VLDB 2023 academic conference talk with no verifiable source, which also contained an implausible inserted marketing reference to 'the data fundamentals certification' inconsistent with an academic database conference talk; and an unverified 'Databricks State of Data + AI report... 87%' statistic with no locatable matching source. De-attributed both quotes, removed the implausible marketing insertion, softened the unverified statistic to qualitative language, and removed the now-orphaned Databricks and Kumar reference-list entries.
