The Pitfalls of Business Rules and Meta Systems (1999) downloads can be found at

Abstract: As people find out that object-orientation and rapid development alone are often not fast enough in order to adapt  software to changing environments and ever changing business processes they turn to meta-systems and try to define business rules in a declarative way. This paper discusses an array of typical design flaws and problems in such systems in order to help you avoid the pitfalls described. Most of the pitfalls described in this paper also contain possible ways to refactor a system once you have identified the problem. Received on Wed Aug 22 2001 - 22:49:04 CEST
