We are investigating on the usability of the new "Switch to your own database schema" feature as it seems an accessible alternative for creating a REST layer on our existing database.

Our "thick database" needs some initialization for each database session to assure that DML statements are executed correctly. In ADF we used to achieve this through some code in the application module's prepareSession method.

I somewhere understood VB business objects are implemented by a layer of ADF Business Components. Configured to operate in a more or less stateless mode, I suppose. That in fact could mean that a prepareSession method is fired on every DML from a VB business object.
