[rules-users] Is Drools appropriate for this app scenario?

[Sebastien Chevalier]

@plugtreelabs: First of all, thank you very much for your response and hints. 

@all: As I'm still not quire sure how to realize my scenario:
Please, could someone provide me with some diagrams or architectural
sketches of a typical rules-based e-commerce web application? -- Or at least
point me to online resources on that topic, especially showing the
integration of the RBMS in a web app?

This would really help me out a lot at the moment.

_Recap: 
The main goal is that endusers shall, on the one hand, define almost the
whole set of entities and rules in an initial shop
specification/configuration process, and on the other hand, this set shall
be modifiable later on (primarily through enhancements, not restrictions).
The entity set basically is: customer types, product categories, products,
product packages, customer(type)-to-product(type) price assignments (i.e.
pricing rules), and inter-product/package selection rules, ...all of these
dynamically definable via a WebUI and in a manner appropriate for
non-technical end-users (considering declarative programming a good approach
for this(?)). 

The most dynamic parts will be the multi-dimensional pricing tables in terms
of (a) their schema -- when new pricing parameters (=dimensions) like
delivery distance are added -- and (b) their value contents -- when concrete
prices change. 
Another quite dynamic part will be the inter-product selection rule
specifications from which a "smart" e-catalog will be generated for the
client-side. Such rules will state sth. like: 
"Prod A must always be ordered with Prod B", "Prod B can never be ordered
when Package C is selected", and similar.

Currently, some "high-level architectural layouts" of a simple, rules-based
e-commerce web app (Which components are necessary in which place? And which
components are already delivered by Drools?) would be very helpful for me.
 
Thank you very much for your help in advance.

Best regards
  Sebastien
