Re: composing multiple bounded contexts in a single user interface

In Revenj we would solve this by defining a report concept which composes all the data sources you need: aggregates, snowflakes (views), events,... 

 And if it was using multiple modules (contexts) it would probably end up in it's own module.
 

 I don't see a need for a session per context (as said in your links) and I certainly want a single call to obtain the data (preferably a single DB call as well).
 

 Even if you are using different applications as different bounded contexts, the answer would still be the same (except that you would actually need to write code in the backend).
