LLCP 2017 Data Lifecycle Timeline

  • Data Collection Begins

    The Behavioral Risk Factor Surveillance System (BRFSS) began collecting health-related data from U.S. adults via phone interviews.
  • Data Stored on Secure Drive

    Survey data from Alabama was stored in CSV format on a secure hard drive located in a locked room to maintain confidentiality and data integrity.
  • Data Transferred to New Facility

    The data set and codebook were copied to a flash drive and physically delivered to the client's new location as part of an expansion effort.
  • Data Imported Into SQL Database

    The dataset was imported into an SQL database at the new facility. However, some unreadable characters caused certain rows to fail during import, resulting in partial data loss.
  • Data Analyst Reviews Import Results

    A newly hired data analyst discovered that the number of rows in the SQL database did not match the original CSV file due to unreadable characters. This initiated a review for missing data and integrity issues.
  • Current Status of Data

    The dataset is currently stored in an SQL database with partial data loss. Analysts are using the codebook and CSV file to identify integrity issues and support ongoing research for healthy heart initiatives in Alabama.
