Oracle SQL Developer and SQL Workshop are two primary ways to move database objects and data from one environment to another, for a single application. Oracle SQL Developer is a graphical tool that allows you to export and import data schemas using Data Pump or SQL scripts. SQL Workshop is a component of Oracle APEX that enables you to perform tasks such as exporting and importing data, running SQL commands, and generating DDL scripts. Both tools can help you migrate your database objects and data to a different instance or workspace.

Session state management is a feature that enables developers to store and retrieve values for a user as the user navigates between different application pages. A session is a logical construct that establishes persistence (or stateful behavior) across page views. Each session is assigned a unique identifier (or session ID). The statement that is true about session state management in Oracle APEX is:

• APEX Sessions are logically and physically distinct from Oracle database sessions used to service page requests. APEX Sessions are stored in memory within an Application Express engine process while Oracle database sessions are stored in memory within an Oracle database process. The other statements are false because:
• A user can run multiple instances of an application simultaneously in different browser programs by using different session IDs.
• Multiple number of sessions can exist in the database at the same time for different users or applications. Verified References: [Understanding Session State Management - Oracle Help Center], [What Is a Session? - Oracle Help Center]

A Progressive Web Application (PWA) is a web application that uses modern web technologies and best practices to provide a native app-like experience to users. Enabling the PWA functionality in your APEX app has the following benefits:

• It optimizes page loading speed on a mobile device by caching static resources and using service workers to handle network requests.
• It adds a new navigation bar entry named Install App to your app, which allows users to install the app on their device’s home screen and access it offline.
• It enhances the app’s appearance and behavior by using a manifest file to specify the app’s name, icon, theme color, orientation, and display mode.

The other options are incorrect because:

• To use the PWA feature, the Friendly URLS attribute in the Application Definition, Properties section must be turned On. This attribute enables user-friendly URLs that are required for PWA functionality.
• PWA features will not be rendered if the application is served in an unsecured environment. The application must use HTTPS protocol to enable PWA functionality.
• You can create a PWA from an existing application or a new application with the Create Application Wizard. You just need to enable the PWA functionality in the User Interface section of the Application Definition.
