Analyzing approaches to integrate Siebel with third party application

We are looking for ways to provide integration solution to our customers where they can connect to our data quality application seamlessly. The idea is to look for script-less methodology where the impact/conflict is least while importing the customized objects in customer's existing application. We are basically looking for a plug and play kind of solution where our application gets deployed in customer environment without any conflicts to their existing customization.

We have already reviewed approach of using universal connector  (SDQ) but found that it has few limitations such as:

– Multiple address list is not supported.

– Personal Address validation is not supported
