During its digital transformation, a healthcare provider wants clinicians to run their own queries in BigQuery. Leadership worries that varying data definitions and unrestricted access could cause reporting errors and violate privacy rules. Which data governance capability most directly mitigates these risks?
Consolidating all information into a single relational database to minimize duplication
Augmenting clinical records by purchasing third-party healthcare datasets
Using only serverless analytics services so administrators do not manage infrastructure
Implementing a centralized data catalog with standardized metadata and role-based access policies
A formal data catalog that stores consistent business and technical metadata lets staff locate the authoritative version of each dataset and understand its approved meaning. When the catalog is integrated with fine-grained access controls, users see only the data they are permitted to view, reducing compliance and privacy risks. Simply moving everything into one database, adding external datasets, or relying on serverless tools does not by itself create common definitions or enforce proper authorization.
