Question

Which of the following is an advantage of UML class diagrams for data modeling that is not possible with EER diagrams?

A. The UML diagram can define methods.
B. UML class diagrams support multiple inheritance, while EER diagrams do not.
C. UML class diagrams are more visually appealing than EER diagrams.
D. UML class diagrams can be used to model complex business processes.

Answer 1

UML class diagrams can define methods, which is an advantage over EER diagrams.

Step-by-step explanation:

The advantage of UML class diagrams for data modeling that is not possible with EER diagrams is that UML class diagrams can define methods. In UML class diagrams, methods can be included along with attributes to represent the behavior of the class. This is not possible with EER diagrams, which are primarily used for conceptual modeling and do not support the definition of methods.
