I need all my cardinalities to be rewritten in a certain format.  They are already have been completed by you just need them to be rewritten like the example below. 

   

So, to describe (in English) Cardinality between two entities, you would provide the following four sentences for the four relationships:

    The two sentences below are examples of how it needs to be written. Mine are currently written with one sentence and they are wrong because of it and not written the same way. Please help 

  (Maximum Cardinality)

·         One INSTRUCTOR can teach MANY CLASS(es) 

·         ONE CLASS can be taught by ONE INSTRUCTOR

(Minimum Cardinality)

·         An INSTRUCTOR is not required to teach a CLASS.

·         A CLASS must have an INSRUCTOR.

 

The two sentences for MAXIMUM Cardinality and the two sentences for MINIMUM Cardinality MUST be used in this course in any discussion of cardinality
