Design ER diagrams for the three problems below based on the information given. Use Visio or another drawing program: I will not grade hand-drawn diagrams. Your diagrams will include entities, attributes, relationships, candidate keys (PKs), and cardinality and participation constraints. Use the style of ER notation shown in the ER slides (also in Elmasri & Navathe, 6th edition, Figure 7.2 and Figure 7.14). Be sure to use good naming practice with your entities, relationships, and attributes. If you make any...
