Hi all,
I have a condition and formula generator in my application. I must save this condition and formula in database and calculate formulas for each condition.
I want to model these conditions and formulas. For example:
Condition:
Education=BS AND MaritalStatus=Married AND YearsOfService>10
Formula:
Salary=2.5*EducationFactor+BaseSalary
I modeled conditions and formula separately and using Interpreter Pattern.
*Condition

*Formula

Now my questions:
1-Are these model Correct?
2-What are context and client in this pattern?
3-In these models , I have to model Coefficients and Items as subclass of Expression, because of Interpreter Pattern, but naturally they aren’t. How can I handle this problem?
4-What are equal tables for these models?
Thanks alot
