Oracle Application Express (APEX) is a feature of Oracle Database, including the Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP) services. An APEX Workspace is a logical domain where you define APEX applications. Each workspace is associated with one or more database schemas (database users) which are used to store the database objects, such as tables, views, packages, and more. APEX applications are built on top of these database objects.
