I have 6 rules for a given 'time' value.
if (0 < iTime <= .5) {iFee = 17}
else if ( .5 < iTime <= 1) {iFee = 20}
else if...
else if...
yada yada
I don't want to code this in C# within my application, or a web service,
because then I have to recompile everytime a user decides to tweek the rules
above. I was thinking that I could create a javascript function and have
the .NET app call it, passing in the iTime, and getting back iFee.
But Javascript is a pain to work with. I'm wondering -- if there's a
derivation of XML -- that can do this. Pass in a value, get back something
else: a rules engine thats easy to modify.
TY for any advice

If the rules are as simple as the example then all you need to store in the
config file is the break levels and the associated fee. The logic engine
can remain in your compiled code as it doesn't actually change - only the
values it uses do.

Dan,
But if I just store the break level, .5, it doesn't tell me if the fee
associated with that is less than, less than or equal, or more than .5.
What if the user decides "I want from 0 to .5 hrs -- not including 5, to be
$17. And .5 to 1 hr to be 20." -- Before it was less than or equal to .5,
now its become less than .5, and if the time equals .5 itself, it goes to
the next tier. This could happen.
If I just store the break values in there I don't have good control, I
somehow need to store the evaluators (<, > etc).
VR,
Jason Shohet

Hi all;
I am using PostgreSQL 7.4 on RedHat 9, though I don't think that is important

I am attempting to write a rule that will check to see whether certain
conditions are right for a SELECT query and abort the query of those
connections are not right. In this case, I am trying to do additional
permissions enforcement. I have written a function to do the checking,
but when I create the rule, I get an error. So here...

All,
I am writing an application that requires a very light weight rules engine.
The core requirement is for me to express a simple rule such as:
If the value of X > 100, send an e-mail
else send a message to a pager
I can do this various ways, e.g., emit code at runtime, etc., but I was
hoping to find a lightweight engine that allows me to express rules simply

Hello all,
I have been using C# in my programming class and I have grown quite fond
of C# properties. Having a method act like a variable that I can control
access to is really something. As well as learning C#, I think that it's way
overdue for me to start learning C++ Templates (I've been learning it for
about 5 years now).
I think that adding this type of functionality would be a good exercise
to help learn template programming....
