General question:

I have an external web service (owned by the company) which my SuD integrates with. I also have relational database:

Client tier --> Web / Business logic tier (middle tier) ----> Data tier

The database sits on the Data tier.. But where would the web service sit in this scenario? Should the data tier actually be an EIS which includes database and web service?? Or is it simply seen as an external system, not part of the main tiers?

Sam, Webservices is a business component. Even if you think WS as interface for data, it could still contain business logic, therefore I would put WS on business tier.

Sam, sorry, you are the provider or consumer of Ws? My message was in case you are ws provider. If you are consuming ws, you can treat it as an external source in integration tier

Eduardo, thanks for your reply.

My SuD simply consumes from the external webservice. The integration logic resides on the integration tier.. But the webservice itself wouldn't actually be part of my tiers, would it?

So, it should be in integration tier -- you're integrating your system with an external source through an end-point WS. And remember to explain that relationship in deploy/component diagram.
