The figure shows the projects_objtab object table with lines connecting the table's attributes projlead_ref
and team_ntab
to an outlying schematic of the people_objtab
object table.
The lines indicate that the attributes of the projects table (projects_objtab
) both use REF
s to pick out rows in the people object table (people_objtab
).
The figure is a graphical representation of the CREATE
TYPE
projects_objtyp
and CREATE
TABLE
projects_objtab
statements that precede the figure in the text.
