DEVELOPMENT OF BROOM
BROOM attempts to combine the strengths of the two approaches: Business Rules
and Object-Oriented Approaches with a modeling language, an appropriate
framework, and integrated support tools. It is supposed to be a lightweight
software development method for building object-oriented business rules systems.
Simply put, a business rules system is an automated system in which the "rules"
are separated (logically, perhaps physically) and shared across data stores, user
interfaces and applications [4, 22, 49].
The next sections are devoted to the development of the different components of
the proposed method – an extension of the UML, framework, and support tools &
techniques.
4.2 EXTENDING UML FOR BROOM
To extend UML, data modeling techniques are used for the fact that persistency of
the business rules is the main concern of the method under development. That is,
our strategy in modeling business rules for the proposed method is first to look at
the business rules repository system level so as to come up with an extended UML
class diagrams that helps us model the artifacts of a business rules software
system.
4.2.1 EXTENDING UML
This process of extending UML is done after proper analysis of UML class diagram
for its necessity, sufficiency, and consistency is carried out. The technique uses
stereotyping extensively for modeling business rule via its flavors: Terms, Facts
