''The applicant will have a good credit score if the applicant has an acceptable number of credit accounts in good standing. The applicant has an acceptable number of credit accounts in good standing if the applicant has 3 or more credit accounts with a positive balance''.
Suppose that you need to model whether the applicant will have a good credit score in a single rule.
What style should ''the applicant has 3 or more credit accounts with a positive balance'' be modeled in?
You are working in a project where you need to develop a rule to calculate the currency attribute ''the person's total taxable income''. The person's total taxable income is either the sum of the attributes ''the person's wages'' and ''the person's interest'' or $50,000, whichever is lower.
