Which type of DDIC contains data related to session management?

The type of DDIC that contains data related to session management is the Session DDIC. This DDIC specifically handles information about user sessions, including maintaining session states, session variables, and other related session data necessary for managing user interactions within an application.

Session management is crucial in any system where multiple users might access the same application concurrently. The Session DDIC ensures that each user's information, such as preferences and activities, is isolated and maintained correctly throughout the user's interaction with the application.

In contrast, other types of DDIC, such as Lookup DDIC, are focused on maintaining reference data or static information for quick access, while Memory DDIC is used for data structures that require fast access and manipulation during the application's runtime. Pillar DDIC typically includes various aspects of a larger data structure or architecture but does not specifically address session management.
