We will also construct an Entity Relationship Diagram (ERD) of the database as we go. Important Note: This is not a description of how you would actually design and implement a database. The sample database screenshots are not meant to be taken literally, but merely as visual aids to show how the raw data gets shuffled about as the table structure becomes increasingly normalized.

The Underline Start and Underline End elements act as milestone tags marking the start and end of overlining that may extend across element boundaries .The underline created using these two elements can have arbitrary start and end points because the start and end elements are paired through the use of the unique identifiers (IDs), not as the start and end of a single element.
