Sample text

Instead, if we assume that the entity F has max-card(F, R) = 1 and thus represents the “many” side of the relationship, the relational table T transformed from the entity F should include columns constituting the primary key for the table transformed from the entity E; this is known as a foreign key in T. Since max-card(F, R) = 1, each row of T is related by a foreign key value to at most one instance of the entity E. If F has mandatory participation in R, then it must be related to exactly one instance of E, and this means that the foreign key in T cannot take on null values.

6(a) has more than one incident connecting line, we record this fact using the notation max-card(E, R) = 1 and max-card(F, R) = 1. 6(b), assuming once again that this set of lines is representative of the designer’s intention, we can write min-card(E, R) = 0, since not every element of E is connected to a line, but min-card(F, R) = 1, since at least one line is connected to every element of F, and our assumption implies that this won’t change. We also write max-card(E, R) = N, where N means “more than one”; this means that the designer does not intend to limit to one the number of lines connected to each entity instance of E.
