Which approach to construct a database to generate external reports across geographic locations by DRG?

This option suggests a database constructed using data specifically identified for research purposes. While useful in certain contexts, this approach does not inherently focus on aggregating or reporting across geographic locations and may not provide the broader overview necessary for external reporting.

De-identified data is anonymized to protect patient privacy, which is crucial for compliance with regulations. However, this method alone does not facilitate the structured aggregation of data needed for comprehensive external reports across geographic regions, limiting its effectiveness in this context.

A flat file database structure organizes data in a single table without any relational connections. This format lacks the ability to efficiently handle complex queries or aggregate data from various locations, making it less suitable for generating detailed external reports that require a more sophisticated data organization.
