Yes, but what do you need the class diagram for?

Then if I dont make class diagram, how can I model it and give it to programmer?

What is my problem?!!
Dear Nachiket,

My application must have features for getting formula from users, validate it and calculate it.
These formulas use in HRM syetem.
How can I model formul with class diagram.

Suppose I have a class named A. This class has a attribute which is a class itself, but it maybe various classes, sometimes B1,sometimes B2 and �.
So,I thought the best model might be like this:
It�s good, because if another class like B3 needed to be added, It�s simple just inherit it from C class.
But the subject is B1, B2 and B3 are not type of C naturally .So what is problem?
Suppose we have similar situation for Z class. it has a attribute which is a class, and might be various class, sometimes B1,Sometimes D1,�..Like this:
It means B1 is inherited from C and E.
Here we have 2 problems:
1-I had to model multi inheritance, that not supporting in my implementing environment and I have to use trick and pattern to do it, and it made more complex.
2-when I want to convert my class diagram to Data model:
I will have a C table with CID for Primary key. And I have B1 and B2 tables too. Related class of them inherited from C class, and then CID is primary key for B1 and B2 tables too.
This story goes for E table and, B1 and D1 Tables too. But in this case B1 table have 2 primaries key CID and EID.

What should I do?
