Drools for Complex Display Value Lookup

The purpose of this quetion is to evaluate the reasonability of using Drools for complex display value lookup processing within a web application. I have been tasked to retrieve coverage inf开发者_JS百科ormation (from an insurance policy) stored in a vendor database and display the information within a custom web app. There are 100s of coverages and the display values that are to be displayed for each coverage can be based on a combination of 4 or 5 different columns per type of coverage. I think there may be as many as 40 different types of coverages.

So with that being said, would drools or a decision tree mechanism provide a good way of handling this? I should point out that it is very likely that we'll need to add / modify the coverage information often and one thing that draws me to this mechanism is that the BAs could help keep the rules up-to-date. I am worried however that the speed may be adversely impacted by this option. Currently I have a working protototype using databases in combination with reflection and XML in the the database to make sure the mapping is done successfully.

I am open to other options if you can think of them as well.

Thanks, Jeremy

Based solely on the fact that you want to offer BAs the possibility to dynamically update the coverage rules, it seems that Drools would offer you a big head start.

Regarding performance, it seems very unlikely to me that the performance would be an issue, as you're talking about a small number of facts and rules really. Biggest performance penalty is usually the parsing of the rules, which can be done on start-up and cached/shared afterward.
