An entity type in a conceptual data model becomes a table in a relational database.

A many$-$to$-$many relationship in a conceptual data model must be implemented as a table in a relational database.

A $1-$to$-$Many relationship in a conceptual data model will be implemented as a matching primary key$-$foreign key combination in a relational database.

A $1-$to$-1$ relationship in a conceptual data model can be implemented as a matching primary key$-$foreign key combination in a relational database. But the foreign key must be the primary key of the table or the foreign key must have a unique index $($constraint$)$ to make the relationship $1-$to$-1$; otherwise, the relationship becomes $1-$to$-$many.

All of the others are TRUE.
