Enterprise Integration & App Mash-up - What is this?

Hi guys, In the Version 4.0 Release Notes it is said: Enterprise Integration & App Mash-up Easily integrate with other Enterprise Apps without the need to move data from one database to another. Mendix can now access information from other apps without having to pull data into your Mendix database. What does this mean? That now, a database associated to a Mendix application can be directly accessed by other Mendix application? Or is this improvement just for integrations and access to external systems? Thanks.

Louis, this means you can call a webservice to another system without saving the response in your own database, because of the non-persistent objects. Non-persisent objects are objects which are not stored into the database but will remain in your app memory.
