Pаrt 1: Entity-Relаtiоnship Mоdel [40 pоints] Design аn Entity-Relationship diagram with ERDPlus by considering the requirements listed in the statements below. That means that you have to identify suitable entity sets, relationship sets, attributes, keys of entity sets, and so on. Further, add the cardinalities (1:1, 1:m, m:1, m:n) to the relationship sets. Write down your thoughts and assumptions regarding the cardinalities if there could be a doubt. It is up to you if you choose Chen's notation or Crow's foot notation. But you have to use the selected notation consistently, that is, you should not mix the two notations. As we all have found out, ERDPlus does not cleanly support both notations. In both notations, ERDPlus uses rectangles for entity sets, double rectangles for weak entity sets, diamonds for relationship sets, double diamonds for identifying relationship sets, ovals for attributes, double ovals for multiple attributes, trees for composite attributes, and trees for generalizations. The only difference that ERDPlus provides to distinguish both notations refers to cardinalities. In Chen's notation, one has to use the labels 1, n, and m for cardinalities (with the known overlapping problem). Double lines are not provided so it is impossible to represent total participation as well as the double line between an identifying relationship set and a weak entity set. You should then describe this in a sentence below the ER diagram. In crow's foot notation, ERDPlus offers the little bar, the little oval, and the crow's foot to indicate cardinalities. The instructor's recommendation is to use the ERDPlus version of Crow's foot notation since it provides all the functionality that you need.
