New AE Analytic Views

Oracle Database 19c, Release Update 19.13, introduces AE ("all edition") analytic views. Each new AE analytic view corresponds to an existing non-AE analytic view. AE views have the same columns as their non-AE counterparts, plus a column that displays the name of the application edition where the editioned object is defined.

The following table lists the new AE analytic views, divided into three categories: analytic view views, attribute dimension views, and hierarchy views. For brevity, only the ALL_ views are listed. The corresponding DBA_ and USER_ views are also available and are documented in this guide.
