Combining Different Business Rules Technologies: A Rationalization

Grosof, Benjamin, Rouvellou, Isabelle, Degenaro, Lou, Chan, Hoi Y., Rasmus, Kevin, Ehnebuske, Dave and McKee, Barbara, "Combining Different Business Rules Technologies: A Rationalization" (October 2001). MIT Sloan Working Paper No. 4190-01.

Abstract:

This paper discusses the very early stages of a project being conducted at IBM research to explore how different rule technologies might be combined or enhanced to offer powerful business solutions. People apply many meanings to the term "business rules." In its simplest form, a business rule is any statement that can be put in the form of "if then". Business rules can be implemented in a computer program by programming if-then statements in-line.

This is very efficient performance-wise, but you have to know exactly what rules need to be place where. If the rules change at a later time, there can be high costs of maintenance. This approach also lends toward inconsistency because people create or change rules without a full understanding of all of the rules or how they might interact

Facts on IBM Software

WebSphere MQ (known as MQSeries until 2002) is IBM's Message Oriented Middleware offering.

It has been repeatedly alleged that in 1997 the NSA had backdoored the export version of Notes, but this is a mis-characterization of what actually happened. Prior to that year, Lotus had been restricted from exporting software that used encryption keys that were longer than 40 bits by United States law. Under an agreement with the US government, Lotus was allowed to start exporting 64 bit keys, so long as 24 bits of each key were recoverable using a special key issued by Lotus to the NSA. The result was that the newer version of Lotus Notes provided stronger protection against industrial espionage than any previous version had been allowed to provide, and it provided no less protection against decryption by the NSA than the previous versions had given. (US export regulations were changed in 2001, so current versions of Lotus products are able to use longer keys and they no longer provide NSA with access to any key bits.)

Rose originated to support Ada programming. It currently supports C++ and Java. Unlike many programming artifacts, which developers retain and maintain, Rose Models merely form a stage in the development of a program
