Hi Jess Experts, I am a JESS newbie and want to understand whether I am writing the below rule in JESS correctly:
We have a User Object and each user has a set of applications associated. Each application has a set of accounts and in turn each account has a set of profiles. User Hierarchy: User {username} List of Applications {Application - {appName, userName}} List of Accounts - { Account - {accountName, appName, username}} List of Profiles - {Profile - {name, accountName, username}} The rule we want to check is If an user has a Profile (name = A) in account 1, Profile (name = B) in the same account (account 1) and Profile (name = C) in account 2, Profile (name = D) in account 2 then fire the rule. Jess Rule: (defrule AFTS_RULE_01 (User (userName ?userName)) (Application (appName ?appName&:(eq ?appName "AFTS")) (userName ?userName)) (Account (accountName ?accountName1) (userName ?userName)) (Profile (name ?name1&:(eq ?name1 "A")) (accountName ?accountName1) (userName ?userName)) (Profile (name ?name2&:(eq ?name2 "B")) (accountName ?accountName1) (userName ?userName)) (Account (accountName ?accountName2&~accountName1) (userName ?userName)) (Profile (name ?name3&:(eq ?name3 "C")) (accountName ?accountName2) (userName ?userName)) (Profile (name ?name4&:(eq ?name4 "D")) (accountName ?accountName2) (userName ?userName)) => (printout t "ATFS Rule satisfied for " ?appName crlf) ) Currently we have introduced a variable username in all the objects to maintain the relationship between the User object and the child objects. Is the above rule representation correct or is there a better way to represent this rule in Jess?
