When retrieving data from a relational database, knowing how the tables are related is critical to ensure you are selecting the correct data. Understanding the database structure and the parent/child record relationship are also important, but not as essential as knowing how the tables are related. Knowing the record address of the data is not necessary for retrieving data from a relational database as the data is retrieved based on the relationships between the tables.
