Assume there is a Persons entity type. Each person has a home address. More than one

person can live at the same home address.

$$ Create two, different E$/$R diagrams to depict Persons and their addresses.

You must model essential properties associate with persons and addresses.

$$ Examine the diagrams you produced for the previous question. Why would

we choose one rather than the other? Assume that we have a

ElectricCompanies entity type. Only one of these companies Supplies

power to each home address. Add that information to each E$/$R diagram.

Remember to use consistent notation to label all semantics you want to

capture in the ER diagram.
