Rule Engines have generally 4 types of rules;
Constraint Rule: We may need to define restriction or limits for some entities. “A customer sales order amount must be lower than 100 if the plant is over capacity ”
Validation Rule: Some validation rules may change over time. “Production order can’t be accepted if current day is Sunday”
Action Rule: Some actions may be triggered. “Send a notification e-mail if a purchase order is over $1000 to boss”.
Computation Rule: Some formula may be executed. “Discount is 20% if customer is Mr. Anderson”
