Consider a database containing information about ancient Egyptian pharaohs and archeology. Create entities and relationships as appropriate for each (independent) situation described below. Information that is true for all of the following ER diagrams: Each pharaoh has a name, a nickname, a birth and a death year. The name is a unique identifier for each pharaoh (Ramses I, Ramses II, Akhenaton, etc.)

Draw an ER diagram that describes it.

1) Some pharaohs were buried in tombs, and some pharaohs were buried in pyramids. For the pharaohs buried in tombs, the database stores the official idenfier of the tomb, plus the latitude and longitude of its location. For pharaohs buried in pyramids, the database stores the name of the pyramid and its type.
