What tool should Mary-Jo use to ensure all data models adhere to data modeling best practices?

• A. DAX Studio
• B. Best Practice Analyzer in Tabular Editor
• C. Performance Analyzer
• D. Query Editor

Answer: (B)

Ensuring data models follow established guidelines is achieved by using a tool that automatically checks the model against a library of rules and flags issues. The Best Practice Analyzer in Tabular Editor does exactly that: it runs a BPA profile against your tabular model and identifies common modeling pitfalls such as naming inconsistencies, relationship problems, inappropriate use of calculated columns versus measures, overly complex calculations, and unnecessary hidden objects. It provides a clear report of violations and recommendations, helping you standardize modeling practices across all models.

Other tools serve different purposes. DAX Studio is focused on writing, testing, and troubleshooting DAX queries and analyzing query performance, not on enforcing modeling guidelines. Performance Analyzer helps diagnose visual and query performance in reports, not the structure and governance of the data model. Query Editor (Power Query Editor) is for data shaping and transformation before the modeling stage, not for validating models against best practices.
