Need proof check for a ER diagram
Hi, I am new to this website and I have an assignment due tomorrow about ERD. It's the basic, I have finished the diagram but I'm not very sure that everything is correct. So please kindly help me proof check my diagram. Thank you.
You have to design a meetings database for the employees of a company. An employee can work for only one department at any given time. There can be meetings between a number of employees, and also department meetings. Meetings must be held in some room. Rooms are located in some building, and have a capacity and some equipment (computer, projector, white board, ...).
Thank you in advance, please help me.

why do some lozenges have a double border and others only one?
why do some lines have arrowheads but others do not?
why are there two curved lines between holds and meeting?
but of far, far more importance, why does every entity seem to have an ID?
