Design an ER schema for the hospital database based on information provided in

task $1,$ and entities defined in $1\mathrm{.}1$ with relationships defined in $1\mathrm{.}2.(10$ points$)$

The ER schema should contain entities with their corresponding attributes, key attributes of

each entity, only binary relationships, their corresponding cardinality ratio, and participation

constraints $($total$/$partial$).$
