I have the answer with the question but I want to remake it with word.

5. Design an ER schema with attributes, primary keys, cardinalities and participation constraints if appropriate.  

For keeping track of information about votes taken in the U.S. House of Representatives during the current two-year

congressional session.  The database needs to keep track of each U.S. STATE’S Name (e.g., Texas, New York,

California) and include the Region of the state (whose domain is {North-east, Midwest, South-east, Southwest,

West}).  Each CONGRESSPERSON in the House of Representatives is described by his or her name, plus the

District represented, the StartDate,  when the congressperson was first elected, and the political  party to which he

or she belongs (whose domain is {Republican, Democrat, Independent, Other}).  The database keeps track of each

BILL (i.e., proposed law), including the BillName, the DateOfVote on the bill, whether the bill PassedOrFailed

(whose domain is {Yes, No}, and the Sponsor (the congressperson(s) who sponsored-that is , proposed-the bill).

The database keeps track of how each congressperson voted on each bill (domain of vote attribute is {Yes, No,

Abstain, Absent}).  Draw an ER schema diagram for this application.  State clearly any assumptions you make.
