Adapter in Integration tier

[Srinivasan Rengan]

People,

I have a quick question. I have a requirement where the facade needs to send an async request to an internal queue.

Now, how should the component diagram look like?

I am showing the queue and also the facade class. But I am not really happy with an idea of showing an interaction between them directly. So I use an adapter class. Now the point is, can i show up the adapter class in the integration tier?

In short,

Facade (BI tier) --> Adapter (INT tier) --> Queue

I cannot use a DAO here because I am making an async request which logically does not sound good with DAO.

Thanks in advance for your help.
Appreciate your replies.

I am not sure why this requires an Adapter ? What you seem to need is simple a class that will communicate with your Queue right ? An Adapter is supposed to call one API is lieu of another. You are not doing that here.

Adaptor lets classes work together that couldn't otherwise because of incompatible interfaces. From what i have understood this does not seem to be the case.
