REMARKS
1. «Dynamic Attributes»
2. «Persistence Operations»
These are all the fields found in the above entity
data models for the list of facts (Table 5), which
can be changed by the user of the system.
As an entity class (i.e., business rules should
persist), it requires to have the following default
methods such as Save (), Delete (), and Get ()
operations for managing facts data in a business
rules repository system.
1. The «Dynamic Attributes» can be treated as built-in structures of the class
for a business rules system.
2. Metamodel Management Tool (MMT) handles the relationships/facts
concept of a business rules system.
4.2.3.3 MODELING RULES
Rules are elements or flavors of business rules that can be expressed as
calculations, constraints, or conditional logic. In other words, rules can:
1. Produce the result of a Calculation,
2. Test Conditions to produce a new fact, or
3. Test a condition to initiate action.
A similar but more formal classification of rules can be found in the next table
(Table 7). As presented in the table, there are five types or categories of rules [22]:
Constraints, Guidelines, Action Enablers, Computations and Inferences.
