Draw an ER diagram representing the following categories Persons: A Person has a name and a social security number (SSN). A Person can not have the same SSN as any other Person. A Person attends one or more Meetings. Rooms: A Room has a room number and a capacity. A Room can not have the same room number as any other Room. A Room is managed by one Department. Meetings: . 0 A Meeting has a starting time. A Meeting has an agenda. A Meeting takes place in a certain Room. Multiple Meetings can not start at the same time in the same Room. For simplicity, do not worry about the duration of a Meeting, only the starting time. A Meeting has one or more Persons in attendance. O Departments: A Department has a name and a department ID (DID). A Department can manage zero or more Rooms. Hints: Do not try to prevent more people attending a meeting than the room capacity allows; this would be done in software logic. Do not try to prevent a person from attending multiple meetings at the same starting time. The problem description does not state this restriction.
