Design and develop a database for a hospital that includes at least:

1.Four to five regular strong entities.

2.One disjoint relationship and one overlap relationship.

3.A union

4.One 1:1, one 1:N, and one N:M relationship of which at least one relationship should be partial and one full.

5.Other notes: Do not emphasize on too many attributes for the entities. Two to three attributes for each entity will be enough. Make sure to include a primary key for each entity. Draw an EER diagram for your project, as per the above specifications.
