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?
Regards
Srinath
