Which DDIC is specifically noted for filling and creating pillar tables?

The answer is correct as the Pillar DDIC, specifically designed for filling and creating pillar tables, serves as the foundational structure for data storage and management within the Avaloq system. Pillar tables are essential because they organize and streamline how data is structured and accessed, particularly in the context of financial services.

Pillar DDIC provides the necessary constructs to define the schema and relationships for the data that is relied upon for accurate reporting and analysis. It effectively allows for efficient data retrieval and ensures that data integrity is maintained throughout various processes. This is pivotal as organizations depend on structured data for making informed decisions.

The other types of DDIC mentioned serve different purposes. For example, the Memory DDIC is typically used for short-term data storage and management tasks, while the Datamart and Flat Datamart focus on specific subsets of data usually optimized for analysis rather than the creation of broader pillar tables. Therefore, the distinction here is key as the Pillar DDIC is uniquely suited for the task specified in the question.
