Database structure
This chapter defines the physical structure of each table, as it exists within the DBMS data dictionary. The name of the relation appears in bold print at the top left and a description of the table at the top right. Bold attributes represent primary keys, italic attributes represent foreign keys, and underlined attributes stand for CSS attributes.
