The CDC collected health-related data via phone interviews across all U.S. states, including Alabama, focusing on risk behaviors, chronic conditions, and preventive care.
-
A subset of BRFSS data specific to Alabama was extracted and stored in CSV format on a secure hard drive for internal analysis.
-
The CSV file and codebook were physically delivered to a new facility using a flash drive, preparing for migration into an SQL database.
-
The CSV file was imported into the new SQL system, but character encoding issues caused some rows to fail, resulting in partial data loss.
-
A newly hired analyst reviewed the import logs and identified a mismatch between the original CSV and the SQL database, prompting a data integrity check.
-
The analyst is now tasked with identifying missing records and reviewing metadata and codebook documentation to assess data quality and completeness.
