My name is Carsten Ziegler and this is my web site. I'm a passionate developer, architect and project manager. My native development environment is ABAP on the brilliant NetWeaver platform. If SE80, SM50 and ST22 sound familiar to you, you can probably understand the pleasure of my work. When I'm not developing I enjoy spending time with my family.
Since March 14, 2005 I am the proud father of twins. They are healthy, and very beautiful.

Business Rules Framework plus (BRFplus) is a Business Rules Management System developed in ABAP. BRFplus allows to separate out fix parts of an application (code) and flexible parts (rules) that are subject to more frequent changes. Typical use cases for BRFplus are decision services, data validation and error correction, derivations and classifications, and calculations. The big advantage of the rules approach is that business users gain transparency. Business logic is not hidden in code but defined in rules. These rules are supposed to be changed and tested by business users without involvement of IT which decreases maintenance and testing costs/time.
More information about BRFplus including screenshots, tutorials, and demos are available in SDN.
