The right candidate understands how relational databases work and has working knowledge on the difference between row vs column based systems as it relates to data warehousing. Because the candidate understands what it means for a database to be considered “infrastructure” as well as a critical “application”, the candidate naturally values planning, communication, and deliberate work in a high risk environment.
