Which two DDIC types are considered special?

The correct answer identifies "Session" and "Lookup" as the two special DDIC types.

In Avaloq, DDIC (Data Dictionary) types are significant for data organization and management within the system. "Session" types pertain to temporary storage that is relevant only during a particular operation or user session, allowing for efficient handling of data without persistent storage overhead. This ephemeral nature of session types makes them special in scenarios where performance and memory usage are of prime concern, particularly in complex transactional environments.

"Lookup" types facilitate the retrieval of data based on specific key values, acting like a quick reference or dictionary for data points. The special nature of lookup types lies in their functionality to streamline data access, improving efficiency and speed when dealing with frequently accessed data. This makes them essential for operations that rely on quick data lookups to support various processes within Avaloq.

Therefore, these two types are recognized as special due to their unique functionalities that enhance data handling and performance within the Avaloq ecosystem.
