[rules-users] Need Design Inputs

Hi, We are currenlty working on a new assignment where we have a requirement where some mapping details are available such as A-->B-->C-->D The relationship goes like this A has multiple values of B.Combination of A and B has multiple values for C and finally combination of A,B,C has multiple values of D. User on selecting A the system needs to display the list of B and selecting a value of B from the list system displays the lsit of C and so on. All the request needs to contacts a web service for retreiving the values. Based on the anlaysis we have close to around 30K combination of A,B,C,D. People adviced me to use Drools for this by maintainning the combination in rules (DRL) files is it ideal for using Drools for this kinda scenario. I could well achieve the same requirement with a dynamic query built and fetch the values from database for each combination. I feel using Drools would increase the development time a lot.Also from a maintenance perspective it might consume lots of effort. Can anyone advice me what to use? also please let me know the PRO's and Cons if any? Thanks Best Regards shanmu "Smile , it improves your face value " ____________________________________________________________________________________ Got a little couch potato?
