Which Appian data design approach is recommended for easier annotation of CDTs?

The recommended approach for easier annotation of Complex Data Types (CDTs) in Appian is the Bottom Up method. This approach emphasizes creating CDTs by first defining the smaller, fundamental data entities and then combining them to form more complex types.

By starting with the atomic elements, it becomes simpler to annotate them effectively, as each piece can be tagged and described based on its specific role or function within the overall data structure. This method enhances clarity and maintainability since each basic element reflects an understandable part of the data model.

In contrast, the other approaches, like Top Down or Hybrid, may involve broader or more abstract data structures initially and could lead to complications in annotating individual elements. These strategies may not provide the same straightforward, granular focus that the Bottom Up approach inherently offers when handling annotations in CDTs.
