I am designing a web application that has several tiers including a
Flex client, Rails server and SAP back-end. The application is an
extension of functionality offered by SAP system. SOAP based web
services are used communicate with the back-end.
I am pondering on the implications of the fact that some of my data
models are likely to be in the back-end and some in the Rails
application and some are distributed (shared) between Rails and the
back-end. I would appreciate any pointers toward relevant knowledge on
this subject and if anyone tried something similar with Rails.
Some of the questions I have to find answers to are:
- How does one use ActiveRecord with shared models?
- What are the implications of this type of distributed design?
- Relevant design patterns.
