Please identify the primary key of each relation and circle each foreign key attribute in order to distinguish it from the primary key. Either draw directed arcs by hand or show the inclusion dependencies that accompany your referential integrity constraints

The following Coarse$-$Granular Design$-$Specific ER diagram involves an application domain that

includes airports, airplanes, and their owners. Map this ER diagram into a series of relation schemas

$($i$.$e$.,$ relations$)$ using the information reducing grammar that we have been discussing in class. Please

identify the primary key of each relation and circle each foreign key attribute in order to

distinguish it from the primary key. Either draw directed arcs by hand or show the inclusion

dependencies that accompany your referential integrity constraints.
