4.1 Externalizing Business Rules with NxBRE
Hard-coded business rules can lead to inflexible applications that are hard to maintain. NxBRE is an open source business rules engine that helps you build more agile systems by externalizing the processing of these rules.
NxBRE started as a C# conversion of Sloan Seaman’s JxBRE and has since been vastly extended. Mainly written by David Dossot, NxBRE is available on SourceForge, where it benefits from the functional and technical feedback of a vibrant community.
NxBRE offers two different engine flavors to better fit the skills and knowledge of developers: the Flow Engine suits the procedural-minded, while the Inference Engine is more oriented toward expert system connoisseurs. All rule files are expressed in XML, which allows for easy editing, validation, and transformation. The Inference Engine also supports rules written in a Prolog-like syntax and comes with a dedicated Stencil for Microsoft Visio 2003 that allows graphical editing of rule bases.
