True or False: Appian developers can create record types by connecting to existing data sources, and they can also create record types and tables from scratch.

The statement is true because Appian provides developers with the flexibility to create record types in multiple ways. Specifically, developers can define new record types by connecting directly to existing data sources, such as databases or external systems, allowing for efficient integration of existing data into the Appian environment. This feature enables users to leverage data that is already being managed elsewhere, streamlining the application development process.

Additionally, Appian allows developers to create record types from scratch, meaning they can define the structure, fields, and characteristics of their records without relying on pre-existing data models. This capability is valuable for scenarios where specific business needs or unique data structures are anticipated that do not align with existing data sources.

Both paths support the goal of building robust applications by offering the ability to manage and display data in a way that meets the organization's requirements, whether utilizing existing data or creating new data definitions entirely.
