Appian Exam ACA100 Topic 1 Question 9 Discussion

A Custom Data Type (CDT) in Appian is primarily used to define the structure of related data. It represents a structured data type composed of multiple fields, and it is often used in process models to define the shape of data that will be passed between different activities or stored in the database.

Custom Data Type (CDT) Overview:

CDTs allow developers to define a complex data structure that can include various data types, such as text, numbers, dates, and even nested CDTs.

They are essential for passing structured data within a process model and between Appian applications and external systems.

Why Not Other Options?:

B . Record: Used to represent a view of data from an external or internal source, focusing on displaying and interacting with that data rather than defining its structure.

C . Constant: Stores a fixed value that can be used throughout the application, but it does not define complex data structures.

D . Expression Rule: Encapsulates logic and calculations but does not define data structures.

Using CDTs ensures that the data used within process models is structured and consistent, enabling robust data handling across the application.
