Title: RE: (ROSE) UML and Business Rules

I would like to extend the subject to business modeling. David Lyalin started this thread wondering whether UML is well suited for describing business rules.   I am wondering whether UML is well suited for business modeling. And by the way, what do you call “business modeling”? and maybe Bryon can explain to us what is business modeling for Rational? Is it just describing business rules? I have read Eriksonn-Penker book, but I would like to have other opinions.   Romuald Restout Software Architect, Recruitsoft   P: 418.524.5665, x 232 E: [EMAIL PROTECTED] W: http://www.recruitsoft.com/   -----Original Message----- From: Richard Brand [mailto:[EMAIL PROTECTED]] Sent: Monday, August 26, 2002 9:58 PM To: Baker, Bryon; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Cc: Buhtz, Greg Subject: RE: (ROSE) UML and Business Rules   Bryon recently wrote "Business rules are captured in a single artifact if you simply have too many to manage. (For example, an application that had a single use case for assessing social security eligibility had over 32,000 business rules imposed by the government.)" In our latest compliance project, our 'artifact' is a complete rulebase developed using Softlaw Corporation's legal expert system. The rulebase uses a sort of boolean logic (values true, false plus an additional "unsure") and has impressive natural language capabilities to assist users at run time (and lawyers during development!) understand what is going on.  Our users can run compliance scenarios arising from government regulation of the Australian Financial Services Industry.  The rulebase has 1,300 logic rules derived primarily from legislation and regulation.  Our database is designed to store complex industry relationships which are mapped to contribute some 3,000 facts which may be needed by the 1,300 rules, in any given senario. The facts used by the rulebase have been tightly integrated with ReqPro, initially to manage the rulebase development.  The integration now is so tight that our data entry screens are generated directly from ReqPro requirements!  See http://programs.rational.com/success/Success_StoryDetail.cfm?ID=247 for more details.  The development team has been around 10 people. For comparison, an Australian social security eligibility system, using the same expert system but without ReqPro, currently has about 160 developers and has, I believe, some 7,000 facts and 4,000 logic rules.
