Data modeling
Defining the data model(s) for an app is essential. Altinn Studio supports importing existing data models and creating new data models.
The data model for an app typically defines the data format either sent to the app owner or presented in the app for the user. Therefore, the data model is essential for a consistent and formal data definition, and the application will use a data model for validation from UI and external systems.
