Can someone perhaps tell me if and when SQL Developer Data Modeler supports analytic views?
no there is no support for Analytic Views. But how do you expect that to be?
We are using them to extract some dependencies in SQL Developer Web, so probably will touch that area in DM desktop too - the extent and time frame are not defined.
You can log enhancement request before we do anything on that thus it will be considered in our work whenever we do it.
