Re: RE: Business Rules approach to design?

i head paul dorsey(from dulcian) speak last night. he was talking about a business rules repository modeller that his company has called 'BRIM'

supposed it will generate the bulk of the code for you. anyone ever work with that?

> I have a growing respect for the business rules approach to system design. For instance, entities and relationships as drawn in a traditional entity/relationship (E/R) diagram are representations of business rules about what data your system will read, update, store and write and how various pieces of that data are related. This is implemented as tables, columns, keys, referencial integrity, constraints, and triggers. However, these same implementation methods and languages also need to include implementations of other business rules that cannot be easily depicted on E/R diagrams, such as entity life cycles and use cases.

One approach that is seeing some success, is to include all business rules in a rule database, and using generators to translate the rules into code. One interesting thing to note is that most of the code associated with the rules has nothing to do with the presentation layer - the GUI that most users see. This means that once you have defined the logical subset of data that a module will use, you can set developers free to "just code" a simple module based on that data - providing that it has good error handling for whatever informational, warning and error messages the code enforcing the rules may send back. Where is this code? In the database and/or application server, not in the Forms or Java or whatever code that provides the GUI.
