What must be included to validate incoming data when creating a new dataset?

To validate incoming data while creating a new dataset in Adobe Experience Platform, it is essential to include a schema. A schema defines the structure of the data, specifying the fields, data types, and relationships within the dataset. It acts as a blueprint that ensures the incoming data conforms to the expected format and contains all necessary attributes to be properly integrated into the platform.

By having a well-defined schema, any incoming data can be validated against this structure. This validation process checks for compliance with the schema's rules, ensuring that the data is clean, consistent, and suitable for analysis. Without a schema, there would be no framework to validate the incoming data, which could lead to issues such as data integrity problems and operational inefficiencies.

Sample data, dataflows, and data mapping serve important roles as well but are not required specifically for the validation phase when setting up a new dataset. Sample data helps in testing and visualizing the dataset, dataflows manage the movement of data, and data mapping aligns fields from one data source to another, but these elements do not inherently validate the structure or integrity of the incoming data itself.
