Re: [rules-users] Re: Is this scenario suitable for using Drools?
without knowing how you are accessing the database your two algorithms come
down to something like:
Alg. 1
max(select max(p) from y, select max(t) from z)
Alg. 2
select min(p) from y + select min(t) from z
which is basically the same as what Michael has proposed.
Personally I think if you are already using Drools then this would fit, but
it wouldn't seem like enough of a reason to introduce Drools on its own.

I've 2 algorithms to calculate the cost of a product. At any one

there is only 1 algorithm in use. Initially algorithm 1 will be the default.
Subsequently, the decision to use which algorithm will depend on customers
feedback. The algorithms are:
Algorithm 1:
Cost = MAX(P1, T1, P2, T2, P3, T3, ...)
Algorithm 2:
Cost = MIN(P1, P2, P3, ...) + MIN(T1, T2, T3, ...)
The values of P1, P2, ... are stored within a database. The number of Ps &
Ts are unknown but can be determined by querying the database, Would drools
be a good option to use to store the algorithms? If so, how could I be able
to retrieve the values of P1, P2, etc from the database from within drools?
Thanks!
