The types of variables recognized in Oracle Analytics Cloud include Presentation and Session variables, making this answer accurate.

Presentation variables are used to manage the way data is displayed to users, allowing for dynamic report and dashboard creation. They can hold values that help in filtering or applying user-selected criteria to visualizations in the application, which enhances the interactiveness and tailored experience of reports.

Session variables, on the other hand, are designed to hold information related to an individual user's session. These variables can store user-specific data that can be reused across different analyses within the same session. Examples include storing user ID or user preferences, which can help customize the user experience further.

This understanding is critical when utilizing Oracle Analytics Cloud to build interactive, user-focused reports and dashboards. By leveraging both Presentation and Session variables, developers can effectively create a more personalized and responsive analytical environment for end users.
