Hi all,
We recently implemented Drools in a mortgage application process. The primary
task of the business rule engine was to determine the fraud risk of an
application. The application is delivered in XML format. We noticed that we
were implementing a lot of data manipulation actions in the drl file itself.
For example, the calculation of total income by calculating the sum of a number
of elements or calculating the distance between two geo-locations based on zip
codes. The actual evaluation rules acted on this 'derived' information.
When looking back the drl file contained a lot of code and looked pretty
complicated compared to the actual evaluation rules. My question is, what is
your opinion on data manipulation or transformation within the drl file? If the
drl file is not the best place for this, what would you suggest for data
manipulation?
Thanks,
Betto
