This page provides a physical model diagram of the database.
By clicking on a table, you can change the target row count for this table, i.e the number of rows that will be inserted in this table.
By clicking on a relation (foreign key), you can change the cardinality of this relation, i.e the min/max number of
foreign rows that can reference a primary row. For instance, a cardinality of
0..2 means that each row
from the primary table may be referenced 0, 1, or 2 times in the foreign table.
Note that the cardinality must be consistent with the target row count of the primary and foreign tables. As a convenience, the accepted range (that respects cardinality constraints) is given for each target row count.
