Enhanced ER Model

The enhanced ER model is an abbreviation for Enhanced Entity-Relationship (EER) model. As you know, the entity-relationship (ER) model is a pictorial illustration of the relationship between various entities of a domain. In the case of a large amount of data with multiple interrelated entities, the ER diagrams become complex and tough to interpret. For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.

where is the problem (i build confusion matrix for my data set).
Given the business rule "An employee may have many degrees." Suppose that an employee has the following degrees. BA, BS, MBA, etc. These degrees could be stored in a single string as a multivalued attribute name EMP_DEGREE in an EMPLOYEE table such as the one shown below: EMP_NUM EMP_LNAME EMP_DEGREE 123 Carter BA, BS, MBA 124 Smith BBA, MBA 125 Jones AS 126 Doe BS, MS, PhD. This design is flawed, so correct it by creating additional table(s) and attributes(s) and show the relationships between them. Show all the data above in your table(s). Add additional data if new attributes were added. Show primary and foreign keys in your table(s).
Why are the relationships mandatory to optional? Shouldn't they be mandatory to mandatory?
